Constructor Detail

RemoteUAAL

public RemoteUAAL(ModuleContext context,
          String node,
          String remote)

Basic constructor. Use this one instead of the UAAL one.

Parameters:

context - The uAAL context

node - The client remote node unique identifier

remote - The client remote node endpoint information.

Method Detail

getCEPsList

public List<String> getCEPsList()

Get the list of context event patterns of subscribers registered so far.

Returns:

The list of URIs of context event patterns of subscribers

getSProfilesList

public List<String> getSProfilesList()

Get the list of service profiles of callees registered so far.

Returns:

The list of URIs of service profiles of callees

subscribeC

public void subscribeC(ContextEventPattern[] p,
              ICListener l)

Description copied from class: UAAL

Subscribes for Context Events and specifies how the events would be handled.

UAAL helper automatically creates a new own internal Context Subscriber each time this method is called. An implementation of ICListener must be passed that will handle the reception of an event that matches the passed patterns. The listener is associated to the patterns: All events that match the patterns are received by the listener (regardless of any other calls to this method). The listener remains active and associated to the patterns until terminate() is called. 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 listener.

Remember that the simplified API in this library ( org.universAAL.support.utils.context packages) can assist you in creating Context Event Patterns.

Overrides:

subscribeC in class UAAL

Parameters:

p - An array of Context Event Patterns describing the Context Events that will be handled by the listener.

l - The listener that will handle the received event that matches the patterns.

isPatternAdded

public boolean isPatternAdded(String uri)

provideS

public void provideS(ServiceProfile[] p,
            ISListener l)

Description copied from class: UAAL

Registers Service Profiles and specifies how the calls to these profiles would be handled.

UAAL helper automatically creates a new own internal Service Callee each time this method is called. An implementation of ISListener must be passed that will handle the call request that matches the provided profiles. The listener is associated to the profiles: All call requests that match the profiles are received by the listener (regardless of any other calls to this method). The listener remains active and associated to the profiles until terminate() is called. 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.

Remember that the simplified API in this library ( org.universAAL.support.utils.service packages) can assist you in creating Service Profiles.

Overrides:

provideS in class UAAL

Parameters:

p - An array of Service Profiles describing the provided services that will be handled by the listener.

l - The listener that will handle the received call request that matches the provided service profiles.

Profile

isProfileAdded

public boolean isProfileAdded(String uri)

terminate

public void terminate()

Description copied from class: UAAL

Closes all uAAL wrapper classes created by this UAAL helper until now (by calling their .close() method) and eliminates them. The reference to the Module Context is maintained, however. This allows to perform new calls to the uAAL features methods, which will create new uAAL wrappers in the helper.

Overrides:

terminate in class UAAL

getRemoteID

public String getRemoteID()

Get the client remote node endpoint information.

Returns:

remote endpoint.

setRemoteID

public void setRemoteID(String remote)

Set the client remote node endpoint information.

Parameters:

remote - endpoint.

createCListener

public ICListener createCListener(String uri)

Use this method to create a Listener to be used in the sendC() method of the Utility API, instead of creating it ex profeso.

Parameters:

uri - The URI of the context event pattern being used for this listener

Returns:

A ICListener

createSListener

public ISListener createSListener(String uri)

Use this method to create a Listener to be used in the callS() method of the Utility API, instead of creating it ex profeso.

Parameters:

uri - The URI of the service profile being used for this listener

Returns:

A ISListener
