public abstract class UtilActuatorCallee
extends ServiceCallee

This is an abstract class for those who want to use the typical services of an actuator (get status, set on, set off) over an ontological service. Classes extending this abstract class will be ServiceCallees which handle by default these 3 services. Those considering using UtilActuator could take advantage of this class if they want only to handle those 3 typical services profiles and no more.

Constructor Detail

UtilActuatorCallee

public UtilActuatorCallee(ModuleContext context,
                          String namespace,
                          Actuator actuator)
                   throws InvalidOntologyUtilException

Default constructor of the class. Takes the same parameters needed by a UtilActuator profile method, in addition to the ModuleContext.

BE CAREFUL: This will only work with actuators that have StatusValue as HAS_VALUE property. Others, like DimmerActuator, will throw an exception.

Parameters:

context - The Module Context of uAAL

namespace - The namespace of your server, ending with the character #

actuator - The ontology instance of the actuator you are controlling. The more properties it has set, the better.

Throws:

InvalidOntologyUtilException - when an actuator is passed that is does not have StatusValue as type restriction of its HAS_VALUE property

Method Detail

handleCall

public ServiceResponse handleCall(ServiceCall call)

Description copied from class: ServiceCallee

The actual service method of the ServiceCallee. It is called by the bus whenever there is a call that need to be serviced by this ServiceCallee.

Specified by:

handleCall in class ServiceCallee

Parameters:

call - the call that needs to be serviced.

Returns:

the result of the call execution.

executeOn

public abstract boolean executeOn()

When a SET ON service request is received, this method is called automatically.

Returns:

true if the actuator could be set to ON

executeOff

public abstract boolean executeOff()

When a SET OFF service request is received, this method is called automatically.
