Method Details

read

public NameSample read()
                throws IOException

Description copied from interface: ObjectStream

Returns the next ObjectStream object. Calling this method repeatedly until it returns null will return each object from the underlying source exactly once.

Specified by:

read in interface ObjectStream<NameSample>

Returns:

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

Throws:

IOException - Thrown if there is an error during reading.

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<NameSample>

Throws:

IOException - Thrown if there is an error during resetting the stream.

UnsupportedOperationException - Thrown if the reset() is not supported. By default, this is the case.

close

public void close()
           throws IOException

Description copied from interface: ObjectStream

Closes the ObjectStream and releases all allocated resources. After close was called, it's not allowed to call ObjectStream.read() or ObjectStream.reset().

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ObjectStream<NameSample>

Throws:

IOException - Thrown if there is an error during closing the stream.
