Examples of org.mule.api.transport.MessageReceiver

org.mule.api.transport.MessageReceiver
MessageReceiver is used to receive data from an external system. Typically an implementation of this interface will also implement the listener interface for the external system. For example to listen to a JMS destination the developer would also implement javax.jms.MessageListener. The endpoint (which creates the MessageReceiver) will then register the receiver with the JMS server. Where a listener interface is not availiable the derived MessageReceiver will implement the code necessary to receive data from the external system. For example, the file endpoint will poll a specified directory for its data.

        InboundEndpoint endpoint = muleContext.getEndpointFactory().getInboundEndpoint(endpointName);
        if (endpoint == null)
        {
            // if we dont find an endpoint for the given name, lets check the
            // servlet receivers
            MessageReceiver receiver = getReceivers().get(endpointName);
            
            if (receiver != null)
            {
                endpoint = receiver.getEndpoint();
            }
        }
        return endpoint;
