public final class FilteringRasterStream extends RasterStream implements IDisposable
RasterFilterto each update of a
RasterStream. Can be used to apply filters to videos and other raster streams as they are updated.
|Constructor and Description|
|Modifier and Type||Method and Description|
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
When overridden in a derived class, updates the raster data associated with the raster stream at the specified time.

protected void finalize() throws Throwable
finalizemethod 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™ 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
finalize method may take any action, including
making this object available again to other threads; the usual purpose
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
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
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.
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.
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

public boolean update(JulianDate time, JulianDate nextTime)
Updatemethod is called, the raster stream contains a raster data buffer defined by the current Attributes (
get) of the stream for updating the raster data. The time parameter provides the current and next
SceneManagertime. Return true if the raster data was updated, otherwise return false.
