    Modifier and Type
    Method
    Description
    Creates and returns a copy of this object.

    • ImageCapabilities

      public ImageCapabilities(boolean accelerated)
      Creates a new object for specifying image capabilities.
      Parameters:
      accelerated - whether or not an accelerated image is desired
  • 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
      Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression:
       x.clone() != x
      will be true, and that the expression:
       x.clone().getClass() == x.getClass()
      will be true, but these are not absolute requirements. While it is typically the case that:
       x.clone().equals(x)
      will be true, this is not an absolute requirement.

      By convention, the returned object should be obtained by calling super.clone. If a class and all of its superclasses (except Object) obey this convention, it will be the case that x.clone().getClass() == x.getClass().

      By convention, the object returned by this method should be independent of this object (which is being cloned). To achieve this independence, it may be necessary to modify one or more fields of the object returned by super.clone before returning it. Typically, this means copying any mutable objects that comprise the internal "deep structure" of the object being cloned and replacing the references to these objects with references to the copies. If a class contains only primitive fields or references to immutable objects, then it is usually the case that no fields in the object returned by super.clone need to be modified.

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