Class TransformAttribute

public final class TransformAttribute extends Object implements Serializable

This class provides a mechanism for using an {@link AffineTransform} as an immutable attribute (for example, in the {@link java.text.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.

Constructor Summary
	TransformAttribute(AffineTransform transform) Creates a new attribute that contains a copy of the given transform.

Method Summary
AffineTransform	getTransform() Returns a copy of the transform contained by this attribute.
boolean	isIdentity() Returns `true` if the transform contained by this attribute is an identity transform, and `false` otherwise.
