public RemoteAPIImpl(ModuleContext ctxt)
ctxt - The uAAL contextpublic void register(String id, String remote) throws APIImplException
RemoteAPIThis method must be called once before any other method. Subsequent calls will only update the remote endpoint reference, not restart the registration.

callbacks will be sent by the serverAPIImplExceptionpublic void sendC(String id, String cevent) throws APIImplException
RemoteAPIThe server will automatically create a Context Publisher if this is the first time the method is called. If the passed event contains ContextProvider information, it is used to instantiate the Publisher. Otherwise the missing information is automatically generated: The Publisher is described as either a Gauge or a Controller depending on if you are providing Services (you called method PROVIDES before). The URI of the Provider is then set to http://ontology.universAAL.org/SimpleUAAL .owl#ContextEventsProvider and it cannot be changed. The pattern that describes the provided events of this provider is empty, which means it can publish any type of event. Notice this Provider info is set ONLY THE FIRST TIME and cannot be changed by later calls.

RemoteAPIThe server will automatically create a new Context Subscriber each time this method is called. All Context Events that match the pattern will be sent back to the client endpoint. Since every call to this method creates a new subscriber, you should be careful with how many times you call this method. Usually, a limited number of subscriptions is needed. Remember that you can combine different patterns to be handled by a single subscriber.

RemoteAPIThe server will automatically create an internal Default Service Caller if this is the first time the method is called. The call to the service is synchronous: this method returns the response of the call straight from Service Bus.

RemoteAPIThe server will automatically create a new Service Callee each time this method is called. All ServiceCalls addressed to this profile will be sent back to the client endpoint. Since every call to this method creates a new callee, you should be careful with how many times you call this method. Usually, a limited number of callees is needed.

RemoteAPIIt frees all associated resources allocated to the client by previous calls. No callbacks will be sent to the client endpoint after this, and no further method calls will be allowed.
unregister in interface RemoteAPIid - The token that uniquely identifies the client remote nodeAPIImplExceptionpublic void unregisterAll()
RemoteAPIThis is only for use when the Remote API module is shutting down. It frees all associated resources allocated to the all client by previous calls. No callbacks will be sent to the client endpoint after this, and no further method calls will be allowed. This avoids uAAL wrappers being kept running in the MW when there is no one to answer to them. Unlike unregister(), it does not throw Exception: if a node fails to be unregistered, an error is logged and it continues with the rest.
