TransformAttribute

• java.lang.Object

Fields Summary
private AffineTransform	transform The AffineTransform for this TransformAttribute, or null if AffineTransform is the identity transform.
public static final TransformAttribute	IDENTITY A TransformAttribute representing the identity transform.
static final long	serialVersionUID

Constructors Summary

public TransformAttribute(AffineTransform transform) Wraps the specified transform. The transform is cloned and a reference to the clone is kept. The original transform is unchanged. If null is passed as the argument, this constructor behaves as though it were the identity transform. (Note that it is preferable to use {@link #IDENTITY} in this case.) param transform the specified {@link AffineTransform} to be wrapped, or null. if (transform != null && !transform.isIdentity()) { this.transform = new AffineTransform(transform); }

Methods Summary
public boolean	equals(java.lang.Object rhs) Returns true if rhs is a TransformAttribute whose transform is equal to this TransformAttribute's transform. param rhs the object to compare to return true if the argument is a TransformAttribute whose transform is equal to this TransformAttribute's transform. since 1.6 try { TransformAttribute that = (TransformAttribute)rhs; if (transform == null) { return that.transform == null; } return transform.equals(that.transform); } catch (ClassCastException e) { } return false;
public java.awt.geom.AffineTransform	getTransform() Returns a copy of the wrapped transform. return a AffineTransform that is a copy of the wrapped transform of this TransformAttribute. AffineTransform at = transform; return (at == null) ? new AffineTransform() : new AffineTransform(at);
public int	hashCode() since 1.6 return transform == null ? 0 : transform.hashCode();
public boolean	isIdentity() Returns true if the wrapped transform is an identity transform. return true if the wrapped transform is an identity transform; false otherwise. since 1.4 return transform == null;
private java.lang.Object	readResolve() if (transform == null || transform.isIdentity()) { return IDENTITY; } return this;
private void	writeObject(java.io.ObjectOutputStream s) // sigh -- 1.3 expects transform is never null, so we need to always write one out if (this.transform == null) { this.transform = new AffineTransform(); } s.defaultWriteObject();
