Constructor Detail

Conll03NameSampleStream

public Conll03NameSampleStream(Conll03NameSampleStream.LANGUAGE lang,
                               ObjectStream<String> lineStream,
                               int types)

Initializes a Conll03NameSampleStream.

Parameters:

lang - The language of the CONLL 03 data.

lineStream - An ObjectStream over the lines in the CONLL 03 data file.

types - The entity types to include in the Name Sample object stream.

Conll03NameSampleStream

public Conll03NameSampleStream(Conll03NameSampleStream.LANGUAGE lang,
                               InputStreamFactory in,
                               int types)
                        throws IOException

Initializes a Conll03NameSampleStream.

Parameters:

lang - The language of the CONLL 03 data.

in - The InputStreamFactory for the input file.

types - The entity types to include in the Name Sample object stream.

Throws:

IOException - Thrown if IO errors occurred.

Method Detail

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.
