Object |
clone() |
Creates and returns a copy of this object. |
boolean |
isAccelerated() |
Returns true if the object whose capabilities are encapsulated in this ImageCapabilities can be or is accelerated. |
boolean |
isTrueVolatile() |
Returns true if the VolatileImage described by this ImageCapabilities can lose its surfaces. |

Object
x
, the expression: will be true, and that the expression:x.clone() != x
will bex.clone().getClass() == x.getClass()
true
, but these are not absolute requirements. While it is typically the case that: will bex.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 (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.
