Method Detail

lookupMatcher

public UnicodeMatcher lookupMatcher(int i)

Supplies default implementation for SymbolTable (no action).

Specified by:

lookupMatcher in interface SymbolTable

Parameters:

i - a 32-bit code point from 0 to 0x10FFFF inclusive.

Returns:

the UnicodeMatcher object represented by the given character, or null if there is no mapping for ch.

Status:

Draft ICU3.8.

applyPropertyAlias

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

Apply a new property alias. Is called when parsing [:xxx=yyy:]. Results are to put into result.

Parameters:

propertyName - the xxx in [:xxx=yyy:]

propertyValue - the yyy in [:xxx=yyy:]

result - where the result is placed

Returns:

true if handled

Status:

Draft ICU3.8.

lookup

public char[] lookup(String s)

Supplies default implementation for SymbolTable (no action).

Specified by:

lookup in interface SymbolTable

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.

Status:

Draft ICU3.8.

parseReference

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

Supplies default implementation for SymbolTable (no action).

Specified by:

parseReference in interface SymbolTable

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.

Status:
