public class ImageCapabilities extends Object implements Cloneable
Capabilities and properties of images.
public ImageCapabilities(boolean accelerated)
Creates a new object for specifying image capabilities.
accelerated- whether or not an accelerated image is desired
public boolean isAccelerated()
true if the object whose capabilities are encapsulated in this
ImageCapabilities can be or is accelerated.
public boolean isTrueVolatile()
true if the
VolatileImage described by this
ImageCapabilities can lose its surfaces.
public Object clone()
Description copied from class:
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() != xwill 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:
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.
clone for class
Object performs a specific cloning operation. First, if the class of this object does not implement the interface
Cloneable, then a
CloneNotSupportedException is thrown. Note that all arrays are considered to implement the interface
Cloneable and that the return type of the
clone method of an array type
T where T is any reference or primitive type. Otherwise, this method creates a new instance of the class of this object and initializes all its fields with exactly the contents of the corresponding fields of this object, as if by assignment; the contents of the fields are not themselves cloned. Thus, this method performs a "shallow copy" of this object, not a "deep copy" operation.
Object does not itself implement the interface
Cloneable, so calling the
clone method on an object whose class is
Object will result in throwing an exception at run time.
