java.lang.Object

eu.clarin.weblicht.wlfxb.tc.xb.TextCorpusStored

eu.clarin.weblicht.wlfxb.io.TextCorpusStreamed

All Implemented Interfaces:

TextCorpus, Closeable, AutoCloseable

public class TextCorpusStreamed
extends TextCorpusStored
implements Closeable

Class TextCorpusStreamed is used for accessing specified annotation layers and (optionally) adding any new annotation layers from/to TextCorpus. 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

TextCorpusStreamed

public TextCorpusStreamed(InputStream inputStream,
                  EnumSet<TextCorpusLayerTag> layersToRead)
                   throws WLFormatException

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

Parameters:

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

layersToRead - the annotation layers of TextCorpus that should be read into this TextCorpusStreamed.

Throws:

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

TextCorpusStreamed

public TextCorpusStreamed(InputStream inputStream,
                  EnumSet<TextCorpusLayerTag> layersToRead,
                  OutputStream outputStream)
                   throws WLFormatException

Creates a TextCorpusStreamed 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.

layersToRead - the annotation layers of TextCorpus that should be read into this TextCorpusStreamed.

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.

TextCorpusStreamed

public TextCorpusStreamed(InputStream inputStream,
                  EnumSet<TextCorpusLayerTag> layersToRead,
                  OutputStream outputStream,
                  boolean outputAsXmlFragment)
                   throws WLFormatException

Creates a TextCorpusStreamed 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.

layersToRead - the annotation layers of TextCorpus that should be read into this TextCorpusStreamed.

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

outputAsXmlFragment - true if the output should not contain xml headers, false otherwise.

Throws:

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

TextCorpusStreamed

public TextCorpusStreamed(InputStream inputStream,
                  EnumSet<TextCorpusLayerTag> layersToRead,
                  OutputStream outputStream,
                  List<MetaDataItem> metaDataToAdd)
                   throws WLFormatException

Creates a TextCorpusStreamed from the given TCF input stream, specified annotation layers, output stream and meta data.

Parameters:

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

layersToRead - the annotation layers of TextCorpus that should be read into this TextCorpusStreamed.

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

metaDataToAdd - meta data to be added to the output TCF.

Throws:

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

Method Detail

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 TextCorpusStreamed 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 TextCorpusStreamed has been closed, adding further annotations will have no effect on the output stream.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Throws:

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