IDENTITY
public static final TransformAttribute IDENTITY
ATransformAttributerepresenting 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 useIDENTITYin this case.)- Parameters:
transform- the specifiedAffineTransformto be wrapped, or null.

Method Detail
-
getTransform
public AffineTransform getTransform()
Returns a copy of the wrapped transform.- Returns:
- an
AffineTransformthat is a copy of the wrapped transform of thisTransformAttribute.
-
isIdentity
public boolean isIdentity()
Returnstrueif the wrapped transform is an identity transform.- Returns:
trueif the wrapped transform is an identity transform;falseotherwise.- Since:
- 1.4
-
hashCode
public int hashCode()
Description copied from class:ObjectAnswers an integer hash code for the receiver. Any two objects which answertruewhen passed to.equalsmust answer the same value for this method.- Overrides:
hashCodein classObject- Returns:
- the receiver's hash.
- Since:
- 1.6

equals
public boolean equals(Object rhs)
Returnstrueif rhs is aTransformAttributewhose transform is equal to thisTransformAttribute's transform.- Overrides:
equalsin classObject- Parameters:
rhs- the object to compare to- Returns:
trueif the argument is aTransformAttributewhose transform is equal to thisTransformAttribute's transform.- Since:
- 1.6
