Class TransformAttribute

java.lang.Object

java.awt.font.TransformAttribute

All Implemented Interfaces:

Serializable

public final class TransformAttribute
extends Object
implements Serializable

This class provides a mechanism for using an AffineTransform as an immutable attribute (for example, in the AttributedString class). Any transform passed to this class is copied before being stored, and any transform handed out by this class is a copy of the stored transform. In this way, it is not possible to modify the stored transform.
