finalize

protected void finalize()
                 throws Throwable

Description copied from class: Object

Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize method to dispose of system resources or to perform other cleanup.

The general contract of finalize is that it is invoked if and when the Java^TM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize method may take any action, including making this object available again to other threads; the usual purpose of finalize, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.

The finalize method of class Object performs no special action; it simply returns normally. Subclasses of Object may override this definition.

The Java programming language does not guarantee which thread will invoke the finalize method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.

After the finalize method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.

The finalize method is never invoked more than once by a Java virtual machine for any given object.

Any exception thrown by the finalize method causes the finalization of this object to be halted, but is otherwise ignored.

Overrides:

finalize in class Object

Throws:

Throwable - the Exception raised by this method

                            java.awt.image.ImageObserver o)

Description copied from class: Toolkit

Prepares an image for rendering.

If the values of the width and height arguments are both -1, this method prepares the image for rendering on the default screen; otherwise, this method prepares an image for rendering on the default screen at the specified width and height.

The image data is downloaded asynchronously in another thread, and an appropriately scaled screen representation of the image is generated.

This method is called by components prepareImage methods.

Information on the flags returned by this method can be found with the definition of the ImageObserver interface.

Overrides:

prepareImage in class sun.awt.SunToolkit

Parameters:

img - the image for which to prepare a screen representation.

w - the width of the desired screen representation, or -1.

h - the height of the desired screen representation, or -1.

o - the ImageObserver object to be notified as the image is being prepared.

Returns:

true if the image has already been fully prepared; false otherwise.

                      java.awt.image.ImageObserver o)

Indicates the construction status of a specified image that is being prepared for display.

If the values of the width and height arguments are both -1, this method returns the construction status of a screen representation of the specified image in this toolkit. Otherwise, this method returns the construction status of a scaled representation of the image at the specified width and height.

This method does not cause the image to begin loading. An application must call prepareImage to force the loading of an image.

This method is called by the component's checkImage methods.

Information on the flags returned by this method can be found with the definition of the ImageObserver interface.

Overrides:

checkImage in class sun.awt.SunToolkit

Parameters:

image - the image whose status is being checked.
