Example 1 with NodeList

use of com.vaadin.client.flow.nodefeature.NodeList in project flow by vaadin.

the class ServerEventHandlerBinder method bindServerEventHandlerNames.

/**
 * Registers all the server event handler names found in the feature with
 * the {@code featureId} in the {@link ServerEventObject} {@code object}.
 * Additionally listens to changes in the feature and updates server event
 * object accordingly.
 *
 * @param objectProvider
 *            the provider of the event object to update
 * @param node
 *            the state node containing the feature
 * @param featureId
 *            the feature id which contains event handler methods
 * @return a handle which can be used to remove the listener for the feature
