GraphemeClusterSegmentFinder

Kotlin |Java

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".

Summary

Inherited constants

From class android.text.SegmentFinder

int

DONE

Return value of previousStartBoundary(int), previousEndBoundary(int), nextStartBoundary(int), and nextEndBoundary(int) when there are no boundaries of the specified type in the specified direction.

Public constructors
`GraphemeClusterSegmentFinder(CharSequence text, TextPaint textPaint)` Constructs a GraphemeClusterSegmentFinder instance for the specified text which uses the provided TextPaint to determine grapheme cluster boundaries.

Public methods
`int`	`nextEndBoundary(int offset)` Returns the character offset of the next text segment end boundary after the specified character offset, or `DONE` if there are none.
`int`	`nextStartBoundary(int offset)` Returns the character offset of the next text segment start boundary after the specified character offset, or `DONE` if there are none.
`int`	`previousEndBoundary(int offset)` Returns the character offset of the previous text segment end boundary before the specified character offset, or `DONE` if there are none.
`int`	`previousStartBoundary(int offset)` Returns the character offset of the previous text segment start boundary before the specified character offset, or `DONE` if there are none.
