public MascNamedEntitySampleStream(ObjectStream<MascDocument> samples)
                            throws IOException

Create a stream of named entity samples from a stream of MascDocuments

Parameters:

samples - a MascDocumentStream

Throws:

IOException

Method Detail

read

public NameSample read()
                throws IOException

Get the next sample of named entities.

Returns:

One sentence together with its named entity annotation

Throws:

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>

Overrides:

close in class FilterObjectStream<MascDocument,NameSample>

Throws:

IOException - if there is an error during closing the stream

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>

Overrides:

reset in class FilterObjectStream<MascDocument,NameSample>

Throws:

IOException - if there is an error during reseting the stream

UnsupportedOperationException
