public abstract class FilterObjectStream<S,T>
extends Object
implements ObjectStream<T>

Abstract base class for filtering ObjectStreams.

Filtering streams take an existing stream and convert its output to something else.

Method Detail

reset

public void reset()
           throws IOException,
                  UnsupportedOperationException

Description copied from interface: ObjectStream

Repositions the stream at the beginning and the previously seen object sequence will be repeated exactly. This method can be used to re-read the stream if multiple passes over the objects are required. The implementation of this method is optional.

Specified by:

reset in interface ObjectStream<T>

Throws:

IOException - if there is an error during reseting the stream

UnsupportedOperationException

close

public void close()
           throws IOException

Description copied from interface: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called its not allowed to call read or reset.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ObjectStream<T>

Throws:

IOException - if there is an error during closing the stream
