Method Detail

read

public File read()
          throws IOException

Description copied from interface: ObjectStream

Specified by:

read in interface ObjectStream<File>

Returns:

the next object or null to signal that the stream is exhausted

Throws:

IOException

reset

public void reset()

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<File>

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.
