java.lang.Objectjava.awt.font.TextLayout.CaretPolicy
public static class TextLayout.CaretPolicy
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.
