Example 30 with IgniteClientDisconnectedException

use of org.apache.ignite.IgniteClientDisconnectedException in project ignite by apache.

the class ClientNodes method reconnect.

void reconnect() {
    Ignite ignite = Ignition.start();
    // tag::reconnect[]
    IgniteCache cache = ignite.getOrCreateCache(new CacheConfiguration<>("myCache"));
    try {
        cache.put(1, "value");
    } catch (IgniteClientDisconnectedException e) {
        if (e.getCause() instanceof IgniteClientDisconnectedException) {
            IgniteClientDisconnectedException cause = (IgniteClientDisconnectedException) e.getCause();
            // Wait until the client is reconnected.
            cause.reconnectFuture().get();
        // proceed
        }
    }
    // end::reconnect[]
    ignite.close();
