GraphemeClusterSegmentFinder

Kotlin |Java

open class GraphemeClusterSegmentFinder : SegmentFinder

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

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