Class TransformAttribute

java.lang.Object
  java.awt.font.TransformAttribute

All Implemented Interfaces:

Serializable

public final class TransformAttribute
extends Object
implements Serializable

The TransformAttribute class provides an immutable wrapper for a transform so that it is safe to use as an attribute.

IDENTITY A TransformAttribute representing the identity transform.

Constructor Summary

TransformAttribute(AffineTransform transform)
Wraps the specified transform.

Method Summary

boolean	equals(Object rhs) Returns true if rhs is a TransformAttribute whose transform is equal to this TransformAttribute's transform.
AffineTransform	getTransform() Returns a copy of the wrapped transform.

Field Detail

IDENTITY

public static final TransformAttribute IDENTITY

A TransformAttribute representing the identity transform.

Since:

1.6

Constructor Detail

TransformAttribute

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 IDENTITY in this case.)

Parameters:

transform - the specified AffineTransform to be wrapped, or null.

Method Detail

getTransform

public AffineTransform getTransform()

Returns a copy of the wrapped transform.

Returns:

a AffineTransform that is a copy of the wrapped transform of this TransformAttribute.

isIdentity

public boolean isIdentity()

Returns true if the wrapped transform is an identity transform.

Returns:

true if the wrapped transform is an identity transform; false otherwise.

Since:

1.4

hashCode

public int hashCode()

Description copied from class: Object

hashCode returns a hash code for this object. The hash code must be equal for two objects a and b if a.equals(b) is true.

The default implementation returns System.identityHashCode(this).

Overrides:

hashCode in class Object

Returns:

a hash code value.

Since:

1.6

equals

public boolean equals(Object rhs)

Returns true if rhs is a TransformAttribute whose transform is equal to this TransformAttribute's transform.

Overrides:

equals in class Object

Parameters:

rhs - the object to compare to

Returns:

true if the argument is a TransformAttribute whose transform is equal to this TransformAttribute's transform.

Since:
