Field Summary

Modifier and Type	Field and Description
private final UID	ackID identifier for gc ack
private final Connection	conn connection associated with ConnectionOutputStream
private DGCAckHandler	dgcAckHandler to store refs to returned remote object until DGC ack is received
private final boolean	resultStream indicates whether output stream is used to marshal results

Constructor Summary

Access	Constructor and Description
pack-priv	ConnectionOutputStream(Connection conn, boolean indicates whether this stream is used to marshal return results resultStream) Constructs an marshal output stream using the underlying stream associated with the connection, the parameter c.

Method Summary

Modifier and Type	Method and Description
pack-priv void	done()
pack-priv DGCAckHandler	getDGCAckHandler() Returns this stream's DGCAckHandler, or null if it doesn't have one (saveObject was not invoked).
pack-priv boolean	isResultStream() Returns true if this output stream is used to marshal return results; otherwise returns false.
pack-priv void	saveObject(Object obj) Saves a reference to the specified object in this stream's DGCAckHandler.

Field Detail

ackID	back to summary
private final UID ackID identifier for gc ack

conn	back to summary
private final Connection conn connection associated with ConnectionOutputStream

dgcAckHandler	back to summary
private DGCAckHandler dgcAckHandler to store refs to returned remote object until DGC ack is received

resultStream	back to summary
private final boolean resultStream indicates whether output stream is used to marshal results

Constructor Detail

ConnectionOutputStream

back to summary

pack-priv ConnectionOutputStream(Connection conn, boolean resultStream) throws IOException

Constructs an marshal output stream using the underlying stream associated with the connection, the parameter c.

Parameters

resultStream:boolean: indicates whether this stream is used to marshal return results

Method Detail

done	back to summary
pack-priv void done()

getDGCAckHandler	back to summary
pack-priv DGCAckHandler getDGCAckHandler() Returns this stream's DGCAckHandler, or null if it doesn't have one (saveObject was not invoked). This method should only be invoked after all objects have been written to the stream, because future objects written may yet cause a DGCAckHandler to be created (by invoking saveObject).

isResultStream	back to summary
pack-priv boolean isResultStream() Returns true if this output stream is used to marshal return results; otherwise returns false.

saveObject	back to summary
pack-priv void saveObject(Object obj) Saves a reference to the specified object in this stream's DGCAckHandler.

writeID	back to summary
pack-priv void writeID() throws IOException
