edu.stanford.nlp.pipeline.CustomAnnotationSerializer

public class CustomAnnotationSerializer
extends AnnotationSerializer

Serializes Annotation objects using our own format. Note[gabor]: This is a lossy serialization! For similar performance, and lossless (or less lossy) serialization see, ProtobufAnnotationSerializer.

Method Detail

saveCorefChain

public static void saveCorefChain(java.io.PrintWriter pw,
                                  int cid,
                                  CorefChain cluster)

Serializes one coref cluster (i.e., one entity).

Parameters:

pw - the buffer

cid - id of cluster to save

cluster - the cluster

write

public java.io.OutputStream write(Annotation corpus,
                                  java.io.OutputStream os)
                           throws java.io.IOException

Description copied from class: AnnotationSerializer

Append a single object to this stream. Subsequent calls to append on the same stream must supply the returned output stream; furthermore, implementations of this function must be prepared to handle the same output stream being passed in as it returned on the previous write.

Specified by:

write in class AnnotationSerializer

Parameters:

corpus - The document to serialize to the stream.

os - The output stream to serialize to.

Returns:

The output stream which should be closed when done writing, and which should be passed into subsequent calls to write() on this serializer.

Throws:

java.io.IOException - Thrown if the underlying output stream throws the exception.

read

public Pair<Annotation,java.io.InputStream> read(java.io.InputStream is)
                                          throws java.io.IOException

Description copied from class: AnnotationSerializer

Read a single object from this stream. Subsequent calls to read on the same input stream must supply the returned input stream; furthermore, implementations of this function must be prepared to handle the same input stream being passed to it as it returned on the previous read.

Specified by:

read in class AnnotationSerializer

Parameters:

is - The input stream to read a document from.

Returns:

A pair of the read document, and the implementation-specific input stream which it was actually read from. This stream should be passed to subsequent calls to read on the same stream, and should be closed when reading completes.

Throws:

java.io.IOException - Thrown if the underlying stream throws the exception.

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

Throws:

java.lang.Exception
