public class GraphemeClusterSegmentFinder
extends SegmentFinder
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 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. |

From class android.text.SegmentFinder abstract 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. | abstract 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. | abstract 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. | abstract 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. | |
From class java.lang.Object Object | clone() Creates and returns a copy of this object. | boolean | equals(Object obj) Indicates whether some other object is "equal to" this one. | void | finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. | final Class<?> | getClass() Returns the runtime class of this Object. | int | hashCode() Returns a hash code value for the object. | final void | notify() Wakes up a single thread that is waiting on this object's monitor. | final void | notifyAll() Wakes up all threads that are waiting on this object's monitor. | String | toString() Returns a string representation of the object. | final void | wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted. | |
