java.lang.Object

eu.clarin.weblicht.wlfxb.io.ExternalDataWithTextCorpusStreamed

public class ExternalDataWithTextCorpusStreamed
extends Object

Class ExternalDataWithTextCorpusStreamed represents TCF TextCorpus and ExternalData annotations. The class is used for accessing specified annotation layers and (optionally) adding any new annotation layers from/to TextCorpus and/or ExternalData. Only specified in the constructor annotation layers are loaded into the memory. In case all the annotation layers should be loaded into the memory, use WLData class.

Constructor Detail

ExternalDataWithTextCorpusStreamed

public ExternalDataWithTextCorpusStreamed(InputStream inputStream,
                                          EnumSet<ExternalDataLayerTag> edLayersToRead,
                                          EnumSet<TextCorpusLayerTag> tcLayersToRead)
                                   throws WLFormatException

Creates a ExternalDataWithTextCorpusStreamed from the given TCF input stream and specified annotation layers.

Parameters:

inputStream - the underlying input stream with linguistic annotations in TCF format.

edLayersToRead - the annotation layers of ExternalData that should be read into this ExternalDataWithTextCorpusStreamed.

tcLayersToRead - the annotation layers of TextCorpus that should be read into this ExternalDataWithTextCorpusStreamed.

Throws:

WLFormatException - if an error in input format or an I/O error occurs.

ExternalDataWithTextCorpusStreamed

public ExternalDataWithTextCorpusStreamed(InputStream inputStream,
                                          EnumSet<ExternalDataLayerTag> edLayersToRead,
                                          EnumSet<TextCorpusLayerTag> tcLayersToRead,
                                          OutputStream outputStream)
                                   throws WLFormatException

Creates a ExternalDataWithTextCorpusStreamed from the given TCF input stream, specified annotation layers and the output stream.

Parameters:

inputStream - the underlying input stream with linguistic annotations in TCF format.

edLayersToRead - the annotation layers of ExternalData that should be read into this ExternalDataWithTextCorpusStreamed.

tcLayersToRead - the annotation layers of TextCorpus that should be read into this ExternalDataWithTextCorpusStreamed.

outputStream - the underlying output stream into which the annotations from the input stream and any new created annotations will be written (in TCF format).

Throws:

WLFormatException - if an error in input format or an I/O error occurs.

Method Detail

getTextCorpus

public TextCorpus getTextCorpus()

Gets TextCorpus.

Returns:

TextCorpus

getExternalData

public ExternalData getExternalData()

Gets ExternalData.

Returns:

ExternalData

close

public void close()
           throws WLFormatException

Closes the input and output streams associated with this object and releases any associated system resources. Before the streams are closed, all in-memory annotations of the ExternalDataWithTextCorpusStreamed and not-processed part of the input stream are written to the output stream. Therefore, it's important to call close() method, so that all the in-memory annotations are saved to the output stream. Once the ExternalDataWithTextCorpusStreamed has been closed, adding further annotations will have no effect on the output stream.

Throws:

WLFormatException - if an error in input format or an I/O error occurs.

toString

public String toString()

Overrides:

toString in class Object
