Class TransformAttribute

java.lang.Object
java.awt.font.TransformAttribute
All Implemented Interfaces:
Serializable

  • Field Details

    • IDENTITY

      public static final TransformAttribute IDENTITY
      A TransformAttribute representing the identity transform.
      Since:
      1.6

  • Constructor Details

    • 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 Details

    • 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.
      Since:
      1.6

    • 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.
      Since:
      1.6
