Class BigDecimalParser

java.lang.Object

tools.jackson.core.io.BigDecimalParser

public final class BigDecimalParser
extends Object

Internal Jackson Helper class used to implement more optimized parsing of BigDecimal for REALLY big values (over 500 characters).

This class is not meant to be used directly. It is designed to be used by Jackson JSON parsers (and parsers for other Jackson supported data formats). The parsers check for invalid characters and the length of the number. Without these checks, this parser is susceptible to performing badly with invalid inputs. If you need to parse numbers directly, please use JavaBigDecimalParser in fastdoubleparser instead.

Based on ideas from this this git commit.

Method Details

parse

public static BigDecimal parse(String valueStr)

Internal Jackson method. Please do not use.

Note: Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Parameters:

valueStr - Value to parse

Returns:

BigDecimal value

Throws:

NumberFormatException - for decoding failures

parse

public static BigDecimal parse(char[] chars,
 int off,
 int len)

Internal Jackson method. Please do not use.

Note: Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Parameters:

chars - Buffer that contains value to parse

off - Offset of the first character to decode

len - Length of value to parse in buffer

Returns:

BigDecimal value

Throws:

NumberFormatException - for decoding failures

parse

public static BigDecimal parse(char[] chars)

Internal Jackson method. Please do not use.

Note: Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Parameters:

chars - Value to parse

Returns:

BigDecimal value

Throws:

NumberFormatException - for decoding failures

parseWithFastParser

public static BigDecimal parseWithFastParser(String valueStr)

Internal Jackson method. Please do not use.

Note: Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Parameters:

valueStr - Value to parse

Returns:

BigDecimal value

Throws:

NumberFormatException - for decoding failures

parseWithFastParser

public static BigDecimal parseWithFastParser(char[] ch,
 int off,
 int len)

Internal Jackson method. Please do not use.

Note: Caller MUST pre-validate that given String represents a valid representation of BigDecimal value: parsers in jackson-core do that; other code must do the same.

Returns:

BigDecimal value

Throws:

NumberFormatException - for decoding failures
