Example 1 with MessageObserver

use of org.eclipse.californium.core.coap.MessageObserver in project leshan by eclipse.

the class CaliforniumLwM2mRequestSender method send.

@Override
public <T extends LwM2mResponse> void send(InetSocketAddress serverAddress, boolean secure, final UplinkRequest<T> request, long timeout, ResponseCallback<T> responseCallback, ErrorCallback errorCallback) {
    // Create the CoAP request from LwM2m request
    CoapRequestBuilder coapClientRequestBuilder = new CoapRequestBuilder(serverAddress);
    request.accept(coapClientRequestBuilder);
    Request coapRequest = coapClientRequestBuilder.getRequest();
    // Add CoAP request callback
    MessageObserver obs = new AsyncRequestObserver<T>(coapRequest, responseCallback, errorCallback, timeout) {

        @Override
        public T buildResponse(Response coapResponse) {
            // Build LwM2m response
            LwM2mClientResponseBuilder<T> lwm2mResponseBuilder = new LwM2mClientResponseBuilder<>(coapResponse);
            request.accept(lwm2mResponseBuilder);
            return lwm2mResponseBuilder.getResponse();
        }
    };
    coapRequest.addMessageObserver(obs);
    // Send CoAP request asynchronously
    if (secure)
        securedEndpoint.sendRequest(coapRequest);
    else

}

Example 2 with MessageObserver

use of org.eclipse.californium.core.coap.MessageObserver in project leshan by eclipse.

the class CaliforniumLwM2mRequestSender method send.

@Override
public <T extends LwM2mResponse> void send(final Registration destination, final DownlinkRequest<T> request, long timeout, ResponseCallback<T> responseCallback, ErrorCallback errorCallback) {
    // Retrieve the objects definition
    final LwM2mModel model = modelProvider.getObjectModel(destination);

    CoapRequestBuilder coapRequestBuilder = new CoapRequestBuilder(destination.getIdentity(), destination.getRootPath(), destination.getId(), destination.getEndpoint(), model, encoder);
    request.accept(coapRequestBuilder);
    final Request coapRequest = coapRequestBuilder.getRequest();

        @Override
        public T buildResponse(Response coapResponse) {

            return lwm2mResponseBuilder.getResponse();
        }
    };
    coapRequest.addMessageObserver(obs);
    // Store pending request to cancel it on de-registration
    addPendingRequest(destination.getId(), coapRequest);
    // Send CoAP request asynchronously
    Endpoint endpoint = getEndpointForClient(destination);
    endpoint.sendRequest(coapRequest);
}

Example 3 with MessageObserver

use of org.eclipse.californium.core.coap.MessageObserver in project leshan by eclipse.

the class CaliforniumLwM2mBootstrapRequestSender method send.

@Override

    final Request coapRequest = coapClientRequestBuilder.getRequest();
    // Add CoAP request callback
    MessageObserver obs = new AsyncRequestObserver<T>(coapRequest, responseCallback, errorCallback, timeout) {

        @Override
        public T buildResponse(Response coapResponse) {
            // TODO we need to fix that by removing the Client dependency from LwM2MResponseBuilder or by creating a
            // LwM2mBootstrapResponseBuilder
            Registration registration = new Registration.Builder("fakeregistrationid", endpointName, destination, destination.isSecure() ? secureEndpoint.getAddress() : nonSecureEndpoint.getAddress()).build();
            // Build LwM2m response
            LwM2mResponseBuilder<T> lwm2mResponseBuilder = new LwM2mResponseBuilder<>(coapRequest, coapResponse, registration, model, null, decoder);
            request.accept(lwm2mResponseBuilder);
            return lwm2mResponseBuilder.getResponse();
        }
    };
    coapRequest.addMessageObserver(obs);
    // Send CoAP request asynchronously
    if (destination.isSecure())
