Method Summary

Modifier and Type	Method	Description
boolean	applyPropertyAlias(String propertyName, String propertyValue, UnicodeSet result)	Override the interpretation of the sequence [:propertyName=propertyValue:] (and its negated and Perl-style variant).
char[]	lookup(String s)	Supplies default implementation for SymbolTable (no action).
UnicodeSet	lookupSet(String s)	Returns a pre-parsed set associated with the variable with the given name, or null if there is no such set (as is the case for an undefined or string-valued variable).
String	parseReference(String text, ParsePosition pos, int limit)	Supplies default implementation for SymbolTable (no action).

Method Details

lookup

public char[] lookup(String s)

Description copied from class: UnicodeSet.XSymbolTable

Supplies default implementation for SymbolTable (no action).

Specified by:

lookup in interface SymbolTable

Overrides:

lookup in class UnicodeSet.XSymbolTable

Parameters:

s - the symbolic name to lookup

Returns:

a char array containing the name's value, or null if there is no mapping for s.

lookupSet

public UnicodeSet lookupSet(String s)

Description copied from interface: SymbolTable

Returns a pre-parsed set associated with the variable with the given name, or null if there is no such set (as is the case for an undefined or string-valued variable).

parseReference

public String parseReference(String text,
 ParsePosition pos,
 int limit)

Description copied from class: UnicodeSet.XSymbolTable

Supplies default implementation for SymbolTable (no action).

Specified by:

parseReference in interface SymbolTable

Overrides:

parseReference in class UnicodeSet.XSymbolTable

Parameters:

text - the text to parse for the name

pos - on entry, the index of the first character to parse. This is the character following the SYMBOL_REF character. On exit, the index after the last parsed character. If the parse failed, pos is unchanged on exit.

limit - the index after the last character to be parsed.

Returns:

the parsed name, or null if there is no valid symbolic name at the given position.

applyPropertyAlias

public boolean applyPropertyAlias(String propertyName,
 String propertyValue,
 UnicodeSet result)

Description copied from class: UnicodeSet.XSymbolTable

Override the interpretation of the sequence [:propertyName=propertyValue:] (and its negated and Perl-style variant). The propertyName and propertyValue may be existing Unicode aliases, or may not be.

This routine will be called whenever the parsing of a UnicodeSet pattern finds such a propertyName+propertyValue combination.

Overrides:

applyPropertyAlias in class UnicodeSet.XSymbolTable

Parameters:

propertyName - the name of the property

propertyValue - the name of the property value

result - UnicodeSet value to change a set to which the characters having the propertyName+propertyValue are to be added.

Returns:

returns true if the propertyName+propertyValue combination is to be overridden, and the characters with that property have been added to the UnicodeSet, and returns false if the propertyName+propertyValue combination is not recognized (in which case result is unaltered).
