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()Returnstrue
if the object whose capabilities are encapsulated in thisImageCapabilities
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()Returnstrue
if theVolatileImage
described by thisImageCapabilities
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
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 objectx
, the expression:x.clone() != x
x.clone().getClass() == x.getClass()
true
, but these are not absolute requirements. While it is typically the case that:x.clone().equals(x)
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 (exceptObject
) obey this convention, it will be the case thatx.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 bysuper.clone
need to be modified.
