Class UTF8DataInputJsonParser

All Implemented Interfaces:
Closeable, AutoCloseable, Versioned

public class UTF8DataInputJsonParser extends JsonParserBase
This is a concrete implementation of JsonParser, which is based on a DataInput as the input source.

Due to limitations in look-ahead (basically there's none), as well as overhead of reading content mostly byte-by-byte, there are some minor differences from regular streaming parsing. Specifically:

  • Input location offsets not being tracked, as offsets would need to be updated for each read from all over the place. If caller wants this information, it has to track this with DataInput. This also affects column number, so the only location information available is the row (line) number (but even that is approximate in case of two-byte linefeeds -- it should work with single CR or LF tho)
  • No white space validation: checks are simplified NOT to check for control characters.

    • releaseBuffered

      public int releaseBuffered(OutputStream out)
      Description copied from class: JsonParser
      Method that can be called to push back any content that has been read but not consumed by the parser. This is usually done after reading all content of interest using parser. Content is released by writing it to given stream if possible; if underlying input is byte-based it can released, if not (char-based) it cannot.
      Overrides:
      releaseBuffered in class JsonParser
      Parameters:
      out - OutputStream to which buffered, undecoded content is written to
      Returns:
      -1 if the underlying content source is not byte based (that is, input cannot be sent to OutputStream; otherwise number of bytes released (0 if there was nothing to release)
    • streamReadInputSource

      public Object streamReadInputSource()
      Description copied from class: JsonParser
      Method that can be used to get access to object that is used to access input being parsed; this is usually either InputStream or Reader, depending on what parser was constructed with. Note that returned value may be null in some cases; including case where parser implementation does not want to exposed raw source to caller. In cases where input has been decorated, object returned here is the decorated version; this allows some level of interaction between users of parser and decorator object.

      In general use of this accessor should be considered as "last effort", i.e. only used if no other mechanism is applicable.

      NOTE: was named getInputSource() in Jackson 2.x.

      Specified by:
      streamReadInputSource in class JsonParser
      Returns:
      Input source this parser was configured with
    • _closeInput

      protected void _closeInput()
      Description copied from class: ParserMinimalBase
      Abstract method for sub-classes to implement; to be called by ParserMinimalBase.close() implementation here.
      Specified by:
      _closeInput in class ParserMinimalBase
    • _releaseBuffers

      protected void _releaseBuffers()
      Method called to release internal buffers owned by the base reader. This may be called along with _closeInput() (for example, when explicitly closing this reader instance), or separately (if need be).
      Overrides:
      _releaseBuffers in class ParserBase
    • getString

      public String getString() throws JacksonException
      Description copied from class: JsonParser
      Method for accessing textual representation of the current token; if no current token (before first call to JsonParser.nextToken(), or after encountering end-of-input), returns null. Method can be called for any token type.
      Specified by:
      getString in class JsonParser
      Returns:
      String value associated with the current token (one returned by JsonParser.nextToken() or other iteration methods)
      Throws:
      JacksonException
    • getString

      public int getString(Writer writer) throws JacksonException
      Description copied from class: JsonParser
      Method to read the textual representation of the current token in chunks and pass it to the given Writer. Functionally same as calling:
        writer.write(parser.getString());
      
      but should typically be more efficient as longer content does need to be combined into a single String to return, and write can occur directly from intermediate buffers Jackson uses.

      NOTE: String value will still be buffered (usually using TextBuffer) and will be accessible with other getString() calls (that is, it will not be consumed). So this accessor only avoids construction of String compared to plain JsonParser.getString() method. Note there is method JsonParser.readString(Writer) that may avoid buffering.

      NOTE: In Jackson 2.x this method was called getText(Writer).

      Overrides:
      getString in class ParserMinimalBase
      Parameters:
      writer - Writer to write String value to
      Returns:
      The number of characters written to the Writer
      Throws:
      JacksonException
    • readString

      public long readString(Writer writer) throws JacksonException
      Description copied from class: JsonParser
      Method to read the textual representation of the current JsonToken.VALUE_STRING token in chunks and stream it directly to the given Writer, without buffering the entire String value in memory. Functionally same as calling:
        writer.write(parser.getString());
      
      but tries to stream the decoded content directly without storing it in TextBuffer, making it suitable for arbitrarily large strings without memory constraints.

      NOTE: whether streaming happens depends on format-specific implementation of this method -- the default implementation delegates to JsonParser.getString(Writer) which does not stream content.

      NOTE: This method consumes the contents of the JsonToken.VALUE_STRING token, advancing the parser state so that the underlying String value is no longer available via JsonParser.getString() or other getString* accessors after this method completes. This differs from JsonParser.getString(Writer) which preserves the buffered string for subsequent access.

      NOTE: This method is primarily intended for very large JSON string values (megabytes or larger) where full buffering would be prohibitive. For typical string sizes, prefer JsonParser.getString() or JsonParser.getString(Writer) which provide more convenient access. The implementation uses an intermediate buffer for efficient bulk writes to the Writer.

      NOTE: This method does enforce StreamReadConstraints.getMaxStringLength() validation during streaming, checking the string length at buffer boundaries and at completion. Strings exceeding the configured limit will result in a StreamConstraintsException.

      NOTE: This method is NOT supported by non-blocking (async) parsers and will throw UnsupportedOperationException if called on such parsers, since content availability is unpredictable in asynchronous parsing mode.

      Overrides:
      readString in class JsonParser
      Parameters:
      writer - Writer to stream the String value to
      Returns:
      The number of characters written to the Writer (as long to support strings exceeding Integer.MAX_VALUE)
      Throws:
      JacksonException
    • getValueAsString

      public String getValueAsString() throws JacksonException
      Description copied from class: JsonParser
      Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation cannot be converted to a String value (including structured types like Objects and Arrays and null token), default value of null will be returned; no exceptions are thrown.
      Overrides:
      getValueAsString in class ParserMinimalBase
      Returns:
      String value current token is converted to, if possible; null otherwise
      Throws:
      JacksonException
    • getValueAsString

      public String getValueAsString(String defValue) throws JacksonException
      Description copied from class: JsonParser
      Method that will try to convert value of current token to a String. JSON Strings map naturally; scalar values get converted to their textual representation. If representation cannot be converted to a String value (including structured types like Objects and Arrays and null token), specified default value will be returned; no exceptions are thrown.
      Overrides:
      getValueAsString in class ParserMinimalBase
      Parameters:
      defValue - Default value to return if conversion to String is not possible
      Returns:
      String value current token is converted to, if possible; def otherwise
      Throws:
      JacksonException
    • getValueAsInt

      public int getValueAsInt() throws JacksonException
      Description copied from class: JsonParser
      Method that will try to convert value of current token to a Java int value. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

      If representation cannot be converted to an int (including structured type markers like start/end Object/Array) default value of 0 will be returned; no exceptions are thrown.

      Overrides:
      getValueAsInt in class ParserMinimalBase
      Returns:
      int value current token is converted to, if possible; default value otherwise otherwise
      Throws:
      JacksonException
    • getValueAsInt

      public int getValueAsInt(int defValue) throws JacksonException
      Description copied from class: JsonParser
      Method that will try to convert value of current token to a int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

      If representation cannot be converted to an int (including structured type markers like start/end Object/Array) specified def will be returned; no exceptions are thrown.

      Overrides:
      getValueAsInt in class ParserMinimalBase
      Parameters:
      defValue - Default value to return if conversion to int is not possible
      Returns:
      int value current token is converted to, if possible; def otherwise
      Throws:
      JacksonException
    • _getText2

      protected final String _getText2(JsonToken t) throws JacksonException
      Throws:
      JacksonException
    • getStringCharacters

      public char[] getStringCharacters() throws JacksonException
      Description copied from class: JsonParser
      Method similar to JsonParser.getString(), but that will return underlying (unmodifiable) character array that contains textual value, instead of constructing a String object to contain this information. Note, however, that:

      Note that caller MUST NOT modify the returned character array in any way -- doing so may corrupt current parser state and render parser instance useless.

      The only reason to call this method (over JsonParser.getString()) is to avoid construction of a String object (which will make a copy of contents).

      Specified by:
      getStringCharacters in class JsonParser
      Returns:
      Buffer that contains the current textual value (but not necessarily at offset 0, and not necessarily until the end of buffer)
      Throws:
      JacksonException
    • getStringLength

      public int getStringLength() throws JacksonException
      Description copied from class: JsonParser
      Accessor used with JsonParser.getStringCharacters(), to know length of String stored in returned buffer.
      Specified by:
      getStringLength in class JsonParser
      Returns:
      Number of characters within buffer returned by JsonParser.getStringCharacters() that are part of textual content of the current token.
      Throws:
      JacksonException
    • getStringOffset

      public int getStringOffset() throws JacksonException
      Description copied from class: JsonParser
      Accessor used with JsonParser.getStringCharacters(), to know offset of the first text content character within buffer.
      Specified by:
      getStringOffset in class JsonParser
      Returns:
      Offset of the first character within buffer returned by JsonParser.getStringCharacters() that is part of textual content of the current token.
      Throws:
      JacksonException
    • getBinaryValue

      public byte[] getBinaryValue(Base64Variant b64variant) throws JacksonException
      Description copied from class: JsonParser
      Method that can be used to read (and consume -- results may not be accessible using other methods after the call) base64-encoded binary data included in the current textual JSON value. It works similar to getting String value via JsonParser.getString() and decoding result (except for decoding part), but should be significantly more performant.

      Note that non-decoded textual contents of the current token are not guaranteed to be accessible after this method is called. Current implementation, for example, clears up textual content during decoding. Decoded binary content, however, will be retained until parser is advanced to the next event.

      Overrides:
      getBinaryValue in class ParserBase
      Parameters:
      b64variant - Expected variant of base64 encoded content (see Base64Variants for definitions of "standard" variants).
      Returns:
      Decoded binary data
      Throws:
      JacksonException
    • readBinaryValue

      public int readBinaryValue(Base64Variant b64variant, OutputStream out) throws JacksonException
      Description copied from class: JsonParser
      Similar to JsonParser.readBinaryValue(OutputStream) but allows explicitly specifying base64 variant to use.
      Overrides:
      readBinaryValue in class JsonParser
      Parameters:
      b64variant - base64 variant to use
      out - Output stream to use for passing decoded binary data
      Returns:
      Number of bytes that were decoded and written via OutputStream
      Throws:
      JacksonException
    • _readBinary

      protected int _readBinary(Base64Variant b64variant, OutputStream out, byte[] buffer) throws IOException
      Throws:
      IOException
    • nextToken

      public JsonToken nextToken() throws JacksonException
      Description copied from class: JsonParser
      Main iteration method, which will advance stream enough to determine type of the next token, if any. If none remaining (stream has no content other than possible white space before ending), null will be returned.
      Specified by:
      nextToken in class JsonParser
      Returns:
      Next token from the stream, if any found, or null to indicate end-of-input
      Throws:
      JacksonException - for low-level read issues
    • _nextToken

      private final JsonToken _nextToken() throws IOException
      Throws:
      IOException
    • _nextTokenNotInObject

      private final JsonToken _nextTokenNotInObject(int i) throws IOException
      Throws:
      IOException
    • _nextAfterName

      private final JsonToken _nextAfterName() throws IOException
      Throws:
      IOException
    • finishToken

      public void finishToken() throws JacksonException
      Description copied from class: JsonParser
      Method that may be used to force full handling of the current token so that even if lazy processing is enabled, the whole contents are read for possible retrieval. This is usually used to ensure that the token end location is available, as well as token contents (similar to what calling, say JsonParser.getStringCharacters(), would achieve).

      Note that for many dataformat implementations this method will not do anything; this is the default implementation unless overridden by sub-classes.

      Overrides:
      finishToken in class ParserMinimalBase
      Throws:
      JacksonException - for low-level read issues
    • nextName

      public String nextName() throws JacksonException
      Description copied from class: JsonParser
      Method that fetches next token (as if calling JsonParser.nextToken()) and verifies whether it is JsonToken.PROPERTY_NAME; if it is, returns same as JsonParser.currentName(), otherwise null.

      NOTE: in Jackson 2.x method was called nextFieldName()

      Overrides:
      nextName in class ParserMinimalBase
      Returns:
      Name of the the JsonToken.PROPERTY_NAME parser advanced to, if any; null if next token is of some other type
      Throws:
      JacksonException - for low-level read issues
    • _nextName

      private final String _nextName() throws IOException
      Throws:
      IOException
    • nextStringValue

      public String nextStringValue() throws JacksonException
      Description copied from class: JsonParser
      Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_STRING returns contained String value; otherwise returns null. It is functionally equivalent to:
        return (nextToken() == JsonToken.VALUE_STRING) ? getString() : null;
      
      but may be faster for parser to process, and can therefore be used if caller expects to get a String value next from input.
      Overrides:
      nextStringValue in class JsonParser
      Returns:
      String value of JsonToken.VALUE_STRING token parser advanced to; or null if next token is of some other type
      Throws:
      JacksonException
    • nextIntValue

      public int nextIntValue(int defaultValue) throws JacksonException
      Description copied from class: JsonParser
      Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 32-bit int value; otherwise returns specified default value It is functionally equivalent to:
        return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getIntValue() : defaultValue;
      
      but may be faster for parser to process, and can therefore be used if caller expects to get an int value next from input.

      NOTE: value checks are performed similar to JsonParser.getIntValue()

      Overrides:
      nextIntValue in class JsonParser
      Parameters:
      defaultValue - Value to return if next token is NOT of type JsonToken.VALUE_NUMBER_INT
      Returns:
      Integer (int) value of the JsonToken.VALUE_NUMBER_INT token parser advanced to; or defaultValue if next token is of some other type
      Throws:
      JacksonException - for low-level read issues
    • nextLongValue

      public long nextLongValue(long defaultValue) throws JacksonException
      Description copied from class: JsonParser
      Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_NUMBER_INT returns 64-bit long value; otherwise returns specified default value It is functionally equivalent to:
        return (nextToken() == JsonToken.VALUE_NUMBER_INT) ? getLongValue() : defaultValue;
      
      but may be faster for parser to process, and can therefore be used if caller expects to get a long value next from input.

      NOTE: value checks are performed similar to JsonParser.getLongValue()

      Overrides:
      nextLongValue in class JsonParser
      Parameters:
      defaultValue - Value to return if next token is NOT of type JsonToken.VALUE_NUMBER_INT
      Returns:
      long value of the JsonToken.VALUE_NUMBER_INT token parser advanced to; or defaultValue if next token is of some other type
      Throws:
      JacksonException
    • nextBooleanValue

      public Boolean nextBooleanValue() throws JacksonException
      Description copied from class: JsonParser
      Method that fetches next token (as if calling JsonParser.nextToken()) and if it is JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE returns matching Boolean value; otherwise return null. It is functionally equivalent to:
        JsonToken t = nextToken();
        if (t == JsonToken.VALUE_TRUE) return Boolean.TRUE;
        if (t == JsonToken.VALUE_FALSE) return Boolean.FALSE;
        return null;
      
      but may be faster for parser to process, and can therefore be used if caller expects to get a Boolean value next from input.
      Overrides:
      nextBooleanValue in class JsonParser
      Returns:
      Boolean value of the JsonToken.VALUE_TRUE or JsonToken.VALUE_FALSE token parser advanced to; or null if next token is of some other type
      Throws:
      JacksonException
    • _parseFloatThatStartsWithPeriod

      protected final JsonToken _parseFloatThatStartsWithPeriod(boolean neg, boolean hasSign) throws IOException
      Throws:
      IOException
    • _parseUnsignedNumber

      protected JsonToken _parseUnsignedNumber(int c) throws IOException
      Initial parsing method for number values. It needs to be able to parse enough input to be able to determine whether the value is to be considered a simple integer value, or a more generic decimal value: latter of which needs to be expressed as a floating point number. The basic rule is that if the number has no fractional or exponential part, it is an integer; otherwise a floating point number.

      Because much of input has to be processed in any case, no partial parsing is done: all input text will be stored for further processing. However, actual numeric value conversion will be deferred, since it is usually the most complicated and costliest part of processing.

      Parameters:
      c - The first non-null digit character of the number to parse
      Returns:
      Type of token decoded, usually JsonToken.VALUE_NUMBER_INT or JsonToken.VALUE_NUMBER_FLOAT
      Throws:
      IOException - for low-level I/O
      StreamReadException - for decoding problems

      private final int _handleLeadingZeroes() throws IOException
      Method called when we have seen one zero, and want to ensure it is not followed by another, or, if leading zeroes allowed, skipped redundant ones.
      Returns:

    • _handleOddName

      protected String _handleOddName(int ch) throws IOException
      Method called when we see non-white space character other than double quote, when expecting a property name. In standard mode will just throw an exception; but in non-standard modes may be able to parse name.

    • currentTokenLocation

      public TokenStreamLocation currentTokenLocation()
      Description copied from class: JsonParser
      Method that return the starting location of the current token; that is, position of the first character from input that starts the current token.

      Note that the location is not guaranteed to be accurate (although most implementation will try their best): some implementations may only return TokenStreamLocation.NA due to not having access to input location information (when delegating actual decoding work to other library).

      Specified by:
      currentTokenLocation in class JsonParser
      Returns:
      Starting location of the token parser currently points to
    • currentLocation

      public TokenStreamLocation currentLocation()
      Description copied from class: JsonParser
      Method that returns location of the last processed character; usually for error reporting purposes.

      Note that the location is not guaranteed to be accurate (although most implementation will try their best): some implementations may only report specific boundary locations (start or end locations of tokens) and others only return TokenStreamLocation.NA due to not having access to input location information (when delegating actual decoding work to other library).

      Specified by:
      currentLocation in class JsonParser
      Returns:
      Location of the last processed input unit (byte or character)
    • _currentLocationMinusOne

      protected TokenStreamLocation _currentLocationMinusOne()
      Description copied from class: ParserMinimalBase
      Factory method used to provide location for cases where we must read and consume a single "wrong" character (to possibly allow error recovery), but need to report accurate location for that character: if so, the current location is past location we want, and location we want will be "one location earlier".

      Default implementation simply returns JsonParser.currentLocation()

      Overrides:
      _currentLocationMinusOne in class ParserMinimalBase
      Returns:
      Same as JsonParser.currentLocation() except offset by -1
