  • Method Details

    • isAccelerated

      public boolean isAccelerated()
      Returns true if the object whose capabilities are encapsulated in this ImageCapabilities can be or is accelerated.
      Returns:
      whether or not an image can be, or is, accelerated. There are various platform-specific ways to accelerate an image, including pixmaps, VRAM, AGP. This is the general acceleration method (as opposed to residing in system memory).
    • isTrueVolatile

      public boolean isTrueVolatile()
      Returns true if the VolatileImage described by this ImageCapabilities can lose its surfaces.
      Returns:
      whether or not a volatile image is subject to losing its surfaces at the whim of the operating system.
    • clone

      public Object clone()
      Description copied from class: Object
      Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.

      Classes which wish to support cloning must specify that they implement the Cloneable interface, since the native implementation checks for this.

      Overrides:
      clone in class Object
      Returns:
      a copy of this ImageCapabilities object.
