handles

public boolean handles(int c)

Specified by:

handles in interface LanguageBreakEngine

Parameters:

c - A Unicode codepoint value

Returns:

true if the engine can handle this character, false otherwise

findBreaks

public int findBreaks(CharacterIterator text,
 int startPos,
 int endPos,
 DictionaryBreakEngine.DequeI foundBreaks,
 boolean isPhraseBreaking)

Description copied from interface: LanguageBreakEngine

Implements the actual breaking logic. Find any breaks within a run in the supplied text.

Specified by:

findBreaks in interface LanguageBreakEngine

Parameters:

text - The text to break over. The iterator is left at the end of the run of characters which the engine has handled.

startPos - The index of the beginning of the range

endPos - The index of the possible end of our range. It is possible, however, that the range ends earlier

foundBreaks - A data structure to receive the break positions.

Returns:

the number of breaks found

setCharacters

void setCharacters(UnicodeSet set)

divideUpDictionaryRange

abstract int divideUpDictionaryRange(CharacterIterator text,
 int rangeStart,
 int rangeEnd,
 DictionaryBreakEngine.DequeI foundBreaks,
 boolean isPhraseBreaking)

Divide up a range of known dictionary characters handled by this break engine.

Parameters:

text - A UText representing the text

rangeStart - The start of the range of dictionary characters

rangeEnd - The end of the range of dictionary characters

foundBreaks - Output of break positions. Positions are pushed. Pre-existing contents of the output stack are unaltered.

Returns:

The number of breaks found
