Examples with GridClientTopology org.apache.ignite.internal.client.impl.connection.GridClientTopology used on opensource projects

Example 1 with GridClientTopology

use of org.apache.ignite.internal.client.impl.connection.GridClientTopology in project ignite by apache.

the class GridRouterClientImpl method forwardMessage.

/**
 * Send a raw packet "as is" directly to the given node.
 * The exact types of acceptable arguments and return values depends on underlying connections.
 *
 * @param msg Raw message to send.
 * @param destId Id of node to send message to. If {@code null} than node will be chosen
 *     from the topology randomly.
 * @return Future, representing forwarded message.
 * @throws GridServerUnreachableException If destination node can't be reached.
 * @throws GridClientClosedException If client is closed.
 * @throws GridClientException If any other client-related error occurs.
 * @throws InterruptedException If router was interrupted while trying.
 *     to establish connection with destination node.
