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.

flushIfNeeded

public void flushIfNeeded(long timeout)
                   throws IOException

Parameters:

timeout - Timeout.
