java.lang.Objectcom.ibm.icu.text.BreakIterator
com.ibm.icu.text.RuleBasedBreakIterator
com.ibm.icu.text.RuleBasedBreakIterator_New
Rule Based Break Iterator implementation. This is a port of the C++ class RuleBasedBreakIterator from ICU4C. A note on future plans: Once a new DictionaryBasedBreakIterator implementation is completed, the archaic implementation class RuleBasedBreakIterator_Old can be completely removed, and this class can be renamed to be simply RuleBasedBreakIterator.

public int getRuleStatus()
Of the standard types of ICU break iterators, only the word break
iterator provides status values. The values are defined in
class RuleBasedBreakIterator, and allow distinguishing between words
that contain alphabetic letters, "words" that appear to be numbers,
punctuation and spaces, words containing ideographic characters, and
more. Call
getRuleStatus
after obtaining a boundary
position from next()
,
previous()
, or
any other break iterator functions that returns a boundary position.
getRuleStatus
in class RuleBasedBreakIterator
public int getRuleStatusVec(int[] fillInArray)
The status values used by the standard ICU break rules are defined as public constants in class RuleBasedBreakIterator.
If the size of the output array is insufficient to hold the data, the output will be truncated to the available length. No exception will be thrown.
getRuleStatusVec
in class RuleBasedBreakIterator
fillInArray
- an array to be filled in with the status values.

public void setText(CharacterIterator newText)
setText
in class RuleBasedBreakIterator
newText
- An iterator over the text to analyze.
