# Class TextLayout.CaretPolicy

java.lang.Object
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.
