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 | Description |
---|---|---|
static final TransformAttribute |
IDENTITY |
A TransformAttribute representing the identity transform. |
Constructor | Description |
---|---|
TransformAttribute |
Wraps the specified transform. |
Modifier and Type | Method | Description |
---|---|---|
boolean |
equals |
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. |
