Method Summary

DataSet	getDataSet() Getter for property dataSet.
boolean	isAsciiTransferTypes() Getter for property asciiTransferTypes.
boolean	isCompressed() Getter for property compressed.
void	setAsciiTransferTypes(boolean asciiTransferTypes) If true, use ascii-type transfer types when creating the stream, so the stream is more easily read by humans and stream-naive parsers.
void	setCompressed(boolean compressed) If true, create a compressed stream.
void	setDataSet(DataSet dataSet) Setter for property dataSet.
void	writeStream(java.io.OutputStream out) convenient method for writing to an OutputStream.
