Example 1 with EndpointDisconnectedEvent

use of com.couchbase.client.core.cnc.events.endpoint.EndpointDisconnectedEvent in project couchbase-jvm-clients by couchbase.

the class BaseEndpointTest method disconnectAfterBeingConnected.

 * signal comes along.

Example 2 with EndpointDisconnectedEvent

use of com.couchbase.client.core.cnc.events.endpoint.EndpointDisconnectedEvent in project couchbase-jvm-clients by couchbase.

the class BaseEndpointTest method disconnectOverridesConnectCompletion.

/**
 * This test makes sure that even if we connect successfully, if there has been a
 * disconnect signal in the meantime we need to properly close it all and not end
 * in a connect-disconnect limbo.
 */

}

Example 3 with EndpointDisconnectedEvent

use of com.couchbase.client.core.cnc.events.endpoint.EndpointDisconnectedEvent in project couchbase-jvm-clients by couchbase.

the class BaseEndpoint method closeChannel.

/**
 * Helper method to close a channel and emit events if needed.

 * state. If one has been there before, it waits until the disconnect future
 * completes.</p>
