|Constructor and Description|
Creates a new object for specifying image capabilities.
|Modifier and Type||Method and Description|
Creates and returns a copy of this object.
public ImageCapabilities(boolean accelerated)
accelerated- whether or not an accelerated image is desired
public boolean isAccelerated()
trueif the object whose capabilities are encapsulated in this
ImageCapabilitiescan be or is accelerated.
public boolean isTrueVolatile()
VolatileImagedescribed by this
ImageCapabilitiescan lose its surfaces.
public Object clone()
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:
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
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
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.
