Class TextLayout.CaretPolicy

  +--java.awt.font.TextLayout.CaretPolicy
Enclosing class:
TextLayout
public static class TextLayout.CaretPolicy
extends Object

Defines a policy for determining the strong caret location. This class contains one method, getStrongCaret, which is used to specify the policy that determines the strong caret in dual-caret text. The strong caret is used to move the caret to the left or right. Instances of this class can be passed to getCaretShapes, getNextLeftHit and getNextRightHit to customize strong caret selection.

To specify alternate caret policies, subclass CaretPolicy and override getStrongCaret. getStrongCaret should inspect the two TextHitInfo arguments and choose one of them as the strong caret.

Most clients do not need to use this class.
