Method Detail

stop

public void stop()

reserveClient

public GridCommunicationClient reserveClient(ClusterNode node,
                                             int connIdx)
                                      throws IgniteCheckedException

Returns existing or just created client to node.

Parameters:

node - Node to which client should be open.

connIdx - Connection index.

Returns:

The existing or just created client.

Throws:

IgniteCheckedException - Thrown if any exception occurs.

createCommunicationClient
