Class SplittingBreakIterator

java.lang.Object

java.text.BreakIterator

org.apache.lucene.search.uhighlight.SplittingBreakIterator

All Implemented Interfaces:

java.lang.Cloneable

public class SplittingBreakIterator
extends java.text.BreakIterator

Virtually slices the text on both sides of every occurrence of the specified character. If the slice is 0-length which happens for adjacent slice characters or when they are at the beginning or end, that character is reported as a boundary. For every slice between the specified characters, it is further processed with a specified BreakIterator. A consequence is that the enclosed BreakIterator will never "see" the splitting character.
Note: setText(CharacterIterator) is unsupported. Use the string version.
