Class TransformAttribute

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

All Implemented Interfaces:

Serializable

public final class TransformAttribute
extends Object
implements Serializable

Disabled: no SafeJ information.

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

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.
int	hashCode() Returns a hash code value for the object.

Field Detail

IDENTITY

public static final TransformAttribute IDENTITY

Class is disabled.

A TransformAttribute representing the identity transform.

Since:

1.6

Constructor Detail

TransformAttribute

public TransformAttribute(AffineTransform transform)

Class is disabled.

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()

Class is disabled.

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()

Class is disabled.

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()

Suppressed. reveals non-deterministic address of object

Description copied from class: Object

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java^TM programming language.)

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.

equals

public boolean equals(Object rhs)

Class is disabled.

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.
