private boolean	accelerated

Access	Constructor and Description
public	ImageCapabilities(boolean whether or not an accelerated image is desired accelerated) Creates a new object for specifying image capabilities.

Method Summary

Modifier and Type	Method and Description
public Object	Returns: a copy of this ImageCapabilities object. clone() Overrides java.lang.Object.clone. Creates and returns a copy of this object.
public boolean	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). isAccelerated() Returns `true` if the object whose capabilities are encapsulated in this `ImageCapabilities` can be or is accelerated.
public boolean	Returns: whether or not a volatile image is subject to losing its surfaces at the whim of the operating system. isTrueVolatile() Returns `true` if the `VolatileImage` described by this `ImageCapabilities` can lose its surfaces.

clone back to summary

clone	back to summary
public Object clone() Overrides java.lang.Object.clone. Doc from java.lang.Object.clone. 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. Returns:Object a copy of this ImageCapabilities object.

Doc from java.lang.Object.clone.

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).

Returns:Object: a copy of this ImageCapabilities object.
