IDENTITY
public static final TransformAttribute IDENTITY
ATransformAttribute
representing the identity transform.- Since:

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 useIDENTITY
in this case.)- Parameters:
transform
- the specifiedAffineTransform
to be wrapped, or null.

Method Detail
-
getTransform
public AffineTransform getTransform()
Returns a copy of the wrapped transform.- Returns:
- an
AffineTransform
that is a copy of the wrapped transform of thisTransformAttribute
.
-
isIdentity
public boolean isIdentity()
Returnstrue
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
Answers an integer hash code for the receiver. Any two objects which answertrue
when passed to.equals
must answer the same value for this method.- Overrides:
hashCode
in classObject
- Returns:
- the receiver's hash.
- Since:
- 1.6

equals
public boolean equals(Object rhs)
Returnstrue
if rhs is aTransformAttribute
whose transform is equal to thisTransformAttribute
's transform.- Overrides:
equals
in classObject
- Parameters:
rhs
- the object to compare to- Returns:
true
if the argument is aTransformAttribute
whose transform is equal to thisTransformAttribute
's transform.- Since:
