Method Detail

close

public void close()
           throws java.io.IOException

Closes the writer and the underlying stream.

writeObjectStart

public void writeObjectStart()
                      throws java.io.IOException

Writes marker signaling start of an object (resp. a document). Will be ignored if underlying implementation doesn't support this kind of marker.

Specified by:

writeObjectStart in interface IpcStreamWriter

Throws:

java.io.IOException - any error

writeMappingEnd

public void writeMappingEnd()
                     throws java.io.IOException
