public final class TransformAttribute extends Object implements Serializable
TransformAttribute class provides an immutable
wrapper for a transform so that it is safe to use as an attribute.| Modifier and Type | Field and Description |
|---|---|
static TransformAttribute |
IDENTITY
A
TransformAttribute representing the identity transform. |
| Constructor and Description |
|---|
TransformAttribute(AffineTransform transform)
Wraps the specified transform.
|
| Modifier and Type | Method and Description |
|---|---|
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.
|
boolean |
isIdentity()
Returns
true if the wrapped transform is
an identity transform. |

ObjectHashMap.
The general contract of hashCode is:
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.
equals(Object)
method, then calling the hashCode method on each of
the two objects must produce the same integer result.
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™ programming language.)
