opennlp.tools.formats.BioNLP2004NameSampleStream

All Implemented Interfaces:

AutoCloseable, ObjectStream<NameSample>

public class BioNLP2004NameSampleStream
extends Object
implements ObjectStream<NameSample>

Parser for the training files of the BioNLP/NLPBA 2004 shared task.

Method Detail

read

public NameSample read()
                throws IOException

Description copied from interface: ObjectStream

Returns the next 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 - 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 - 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<NameSample>

Throws:

IOException - if there is an error during closing the stream
