Field Details

EMPTY

public static final Uri EMPTY

Empty URI.

Method Details

uri

public static Uri uri(byte[] value)

Creates a new uri instance.

Parameters:

value - value

Returns:

uri instance

uri

public static Uri uri(String value)

Creates a new uri instance.

Parameters:

value - string value

Returns:

uri instance

uri

public static Uri uri(byte[] value,
 boolean normalize)

Creates a new uri instance.

Parameters:

value - value

normalize - chop leading and trailing whitespaces

Returns:

uri instance

eq

public boolean eq(Uri uri)

Checks the URIs for equality.

Parameters:

uri - to be compared

Returns:

result of check

resolve

public Uri resolve(Uri add,
 InputInfo ii)
            throws QueryException

Appends the specified address. If one of the URIs is invalid, the original uri is returned.

Parameters:

add - address to be appended

ii - input info

Returns:

new uri

Throws:

QueryException - query exception

isAbsolute

public boolean isAbsolute()

Tests if this is an absolute URI.

Returns:

result of check

isValid

public boolean isValid()

Checks the validity of this URI.

Returns:

result of check

string

public byte[] string(InputInfo ii)

Description copied from class: Item

Returns a string representation of the value.

Specified by:

string in class Item

Parameters:

ii - input info (can be null)

Returns:

string value

string

public byte[] string()

Returns the string value.

Returns:

string value

simplifyFor

public Expr simplifyFor(CompileContext.Simplify mode,
 CompileContext cc)

Description copied from class: Expr

This function is called at compile time for expressions whose operands might be simplified.

Overrides:

simplifyFor in class Expr

Parameters:

mode - mode of simplification

cc - compilation context

Returns:

simplified or original expression

See Also:

• CompileContext.Simplify

toJava

public URI toJava()
           throws QueryException

Description copied from class: Value

Returns a Java representation of the value.

Specified by:

toJava in class Value

Returns:

Java object

Throws:

QueryException - query exception

equals

public boolean equals(Object obj)

Description copied from class: Expr

This function is e.g. called by:

• If.optimize(CompileContext), Switch.optimize(CompileContext), Typeswitch.optimize(CompileContext), in order to discard identical expressions.
• CmpR.mergeEbv(Expr, boolean, CompileContext) or CmpSR.mergeEbv(Expr, boolean, CompileContext), in order to merge expressions with identical input.
• CmpG.optimize(CompileContext) or CmpV.optimize(CompileContext), in order to pre-evaluate equality tests.
• CmpG.optimize(CompileContext) or Pos.get(Expr, CmpV.OpV, InputInfo, CompileContext), in order to compare the start and end value.
• PathCache, in order to find identical root values at runtime.

Overrides:

equals in class AStr
