Class TransformAttribute

java.lang.Object
  extended by 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.

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
Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable.

The general contract of hashCode is:

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 JavaTM programming language.)

Overrides:
hashCode in class Object
Returns:
a hash code value for this object.
Since:
1.6

Object.equals(java.lang.Object), Hashtable

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:
1.6

Object.hashCode(), Hashtable
