GraphemeClusterSegmentFinder


public class GraphemeClusterSegmentFinder
extends SegmentFinder

java.lang.Object
   ↳ android.text.SegmentFinder
     ↳ android.text.GraphemeClusterSegmentFinder


Implementation of SegmentFinder using grapheme clusters as the text segment. Whitespace characters are included as segments.

For example, the text "a pot" would be divided into five text segments: "a", " ", "p", "o", "t".
