Method Details

read

public BratAnnotation read()
                    throws IOException

Description copied from interface: ObjectStream

Specified by:

read in interface ObjectStream<BratAnnotation>

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

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<BratAnnotation>

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<BratAnnotation>
