public final class TransformAttribute
The TransformAttribute class provides an immutable
wrapper for a transform so that it is safe to use as an attribute.
| Field Summary | |
|---|---|
static TransformAttribute |
IDENTITY
A TransformAttribute representing the identity transform. |
| Constructor Summary | |
|---|---|
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. |
boolean |
isIdentity()
Returns true if the wrapped transform is
an identity transform. |

public AffineTransform getTransform()
AffineTransform that is a copy of the wrapped
transform of this TransformAttribute.public boolean isIdentity()
true if the wrapped transform is
an identity transform.
true if the wrapped transform is
an identity transform; false otherwise.public int hashCode()
Objectjava.util.Hashtable.
The general contract of hashCode is:
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 hashtables.
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.)
