Sets the stream to which the message (or message part) downloaded from the server will be written.
public void setMessageStream(java.io.OutputStream messageStream);
This method sets the stream to which the message (or message part) downloaded from the server will be written. If a download stream is set before the Retrieve method is called, the downloaded data will be written to the stream. The stream should be open and normally set to position 0. The class will automatically close this stream if CloseStreamAfterTransfer is true (default). If the stream is closed, you will need to call SetMessageStream again before calling Retrieve again. The downloaded content will be written starting at the current position in the stream.
Note: SetMessageStream and LocalFile will reset the other.
