Example 1 with UiMessageHandler

use of org.onosproject.ui.UiMessageHandler in project onos by opennetworkinglab.

the class UiWebSocket method onWebSocketText.

@Override
public void onWebSocketText(String data) {
    lastActive = System.currentTimeMillis();
    try {
        ObjectNode message = (ObjectNode) mapper.reader().readTree(data);
        String type = message.path(EVENT).asText(UNKNOWN);
        if (sessionToken == null) {
            authenticate(type, message);
        } else {
            UiMessageHandler handler = handlers.get(type);
            if (handler != null) {
                log.debug("RX message: {}", message);
                handler.process(message);
            } else {
                log.warn("No GUI message handler for type {}", type);
            }
        }
    } catch (Error | Exception e) {
        log.warn("Unable to parse GUI message {} due to", data, e);
        log.debug("Boom!!!", e);
    }
}
