| void org.ros.node.NodeListener.onError | ( | Node | node, |
| Throwable | throwable | ||
| ) |
Called when the Node experiences an unrecoverable error.
- Parameters:
-
node the Node that experienced the error throwable the Throwable describing the error condition
Implemented in org.ros.node.DefaultNodeMainExecutor.RegistrationListener, org.ros.MessageSerializationTestNode, org.ros.node.AbstractNodeMain, and org.ros.node.DefaultNodeListener.
| void org.ros.node.NodeListener.onShutdown | ( | Node | node | ) |
Called when the ConnectedNode has started shutting down. Shutdown will be delayed, although not indefinitely, until all NodeListeners have returned from this method.
Since this method can potentially delay ConnectedNode shutdown, it is preferred to use onShutdownComplete(Node) when ConnectedNode resources are not required during the method call.
- Parameters:
-
node the Node that has started shutting down
Implemented in org.ros.node.DefaultNodeMainExecutor.RegistrationListener, org.ros.MessageSerializationTestNode, org.ros.node.AbstractNodeMain, and org.ros.node.DefaultNodeListener.
| void org.ros.node.NodeListener.onShutdownComplete | ( | Node | node | ) |
Called when the Node has shut down.
- Parameters:
-
node the Node that has shut down
Implemented in org.ros.node.DefaultNodeMainExecutor.RegistrationListener, org.ros.MessageSerializationTestNode, org.ros.node.AbstractNodeMain, and org.ros.node.DefaultNodeListener.
| void org.ros.node.NodeListener.onStart | ( | ConnectedNode | connectedNode | ) |
Called when the Node has started and successfully connected to the master.
- Parameters:
-
connectedNode the ConnectedNode that has been started
Implemented in org.ros.node.DefaultNodeMainExecutor.RegistrationListener, org.ros.ParameterServerTestNode, org.ros.rosjava_tutorial_pubsub.Listener, org.ros.MessageSerializationTestNode, org.ros.rosjava_tutorial_services.Server, org.ros.rosjava_tutorial_right_hand_rule.RightHandRule, org.ros.node.AbstractNodeMain, and org.ros.node.DefaultNodeListener.
