Class TransformAttribute

  • All Implemented Interfaces:
    Serializable

    public final class TransformAttribute
    extends Object
    implements Serializable
    The TransformAttribute class provides an immutable wrapper for a transform so that it is safe to use as an attribute.

      • IDENTITY

        public static final TransformAttribute IDENTITY
        A TransformAttribute representing the identity transform.
        Since:
        1.6
    • 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 use IDENTITY in this case.)
        Parameters:
        transform - the specified AffineTransform 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 this TransformAttribute.
      • isIdentity

        public boolean isIdentity()
        Returns true 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 answer true when passed to .equals must answer the same value for this method.
        Overrides:
        hashCode in class Object
        Returns:
        the receiver's hash.

      • equals

        public boolean equals​(Object rhs)
        Returns true if rhs is a TransformAttribute whose transform is equal to this TransformAttribute's transform.
        Overrides:
        equals in class Object
        Parameters:
        rhs - the object to compare to
        Returns:
        true if the argument is a TransformAttribute whose transform is equal to this TransformAttribute's transform.
