Method Detail

doHandshake

public void doHandshake(GridInClosure2X<InputStream,OutputStream> handshakeC)
                 throws GridException

Executes the given handshake closure on opened client passing underlying IO streams. This method pulled to client interface a handshake is only operation requiring access to both output and input streams.

Parameters:

handshakeC - Handshake.

Throws:

GridException - If handshake failed.

close

public boolean close()

Specified by:

close in interface GridCommunicationClient

Overrides:

close in class GridAbstractCommunicationClient

Returns:

True if client has been closed by this call, false if failed to close client (due to concurrent reservation or concurrent close).

forceClose

public void forceClose()

Forces client close.

Specified by:

forceClose in interface GridCommunicationClient

Overrides:

forceClose in class GridAbstractCommunicationClient

sendMessage

               UUID nodeId,
               GridTcpCommunicationMessageAdapter msg)
                 throws GridException

Parameters:

nodeId - Node ID (provided only if versions of local and remote nodes are different).

msg - Message to send.

Throws:

GridException - If failed.

sendMessage

public void sendMessage(ByteBuffer data)
                 throws GridException

Parameters:

data - Data to send.

Throws:

GridException - If failed.

flushIfNeeded

public void flushIfNeeded(long timeout)
                   throws IOException

Parameters:

timeout - Timeout.
