This class implements a CapabilityAgent that handles the Alexa.PowerContoller Interface.

Member Typedef Documentation

◆ EndpointIdentifier

using alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::EndpointIdentifier = avsCommon::sdkInterfaces::endpoints::EndpointIdentifier

Alias to improve readability.

◆ PowerState

using alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::PowerState = avsCommon::sdkInterfaces::powerController::PowerControllerInterface::PowerState

Member Function Documentation

◆ cancelDirective()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::cancelDirective ( std::shared_ptr< DirectiveInfo > info )

overridevirtual

Cancel an ongoing preHandleDirective() or handleDirective() operation for the AVSDirective in . Once this has been called the CapabilityAgent should not expect to receive further calls regarding this directive.

Note: The implementation of this method MUST be thread-safe.; The implementation of this method MUST return quickly. Failure to do so blocks the processing of subsequent AVSDirectives.

Parameters

info	The `DirectiveInfo` instance for the `AVSDirective` to process.

Implements alexaClientSDK::avsCommon::avs::CapabilityAgent.

◆ canStateBeRetrieved()

bool alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::canStateBeRetrieved ( )

overridevirtual

Returns whether the provider can be queried for its state / properties. If not, the provider is omitted from the context altogether. ContextManager will not query or report its state.

Returns: Whether this provider can be queried about its state when a new context request arrives.

Note: In future versions, this method will be made pure virtual.

Reimplemented from alexaClientSDK::avsCommon::sdkInterfaces::StateProviderInterface.

◆ create()

static std::shared_ptr<PowerControllerCapabilityAgent> alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::create	(	const EndpointIdentifier &	endpointId,
		std::shared_ptr< avsCommon::sdkInterfaces::powerController::PowerControllerInterface >	powerController,
		std::shared_ptr< avsCommon::sdkInterfaces::ContextManagerInterface >	contextManager,
		std::shared_ptr< avsCommon::sdkInterfaces::AlexaInterfaceMessageSenderInterface >	responseSender,
		std::shared_ptr< avsCommon::sdkInterfaces::ExceptionEncounteredSenderInterface >	exceptionSender,
		bool	isProactivelyReported,
		bool	isRetrievable
	)

static

Create an instance of PowerControllerCapabilityAgent.

Parameters

endpointId	A endpoint to which this capability is associated.
powerController	An interface that this object will use to perform the power controller operations.
contextManager	An interface to which this object will send property state updates.
responseSender	An interface that this object will use to send the reponse to AVS.
exceptionSender	An interface to report exceptions to AVS.
isProactivelyReported	Whether the power state property change is proactively reported to Alexa in a change report.
isRetrievable	Whether the power state property can be retrieved when Alexa sends a state report request to the endpoint.

Returns: nullptr if the inputs are invalid, else a new instance of PowerControllerCapabilityAgent.

◆ getCapabilityConfiguration()

avsCommon::avs::CapabilityConfiguration alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::getCapabilityConfiguration ( )

Get the capability configuration for this agent.

Returns: The capability configuration.

◆ getConfiguration()

avsCommon::avs::DirectiveHandlerConfiguration alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::getConfiguration ( ) const

overridevirtual

Returns the configuration of the directive handler.

The configuration consists of multiple directive routing rules and their respective blocking policy. The directives will be matched from the most specific rule (with all fields defined) to the least specific rule (which only matches the directive endpointId).

Returns: The avs::DirectiveHandlerConfiguration of the handler.

Implements alexaClientSDK::avsCommon::sdkInterfaces::DirectiveHandlerInterface.

◆ handleDirective()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::handleDirective ( std::shared_ptr< DirectiveInfo > info )

overridevirtual

Handle the action specified by the AVSDirective in info. The handling of subsequent directives with the same DialogRequestId may be blocked until the DirectiveHandler calls the setSucceeded() method of the DirectiveHandlingResult present in info. If handling of this directive fails setFailed() should be called to indicate a failure.

Note: The implementation of this method MUST be thread-safe.; The implementation of this method MUST return quickly. Failure to do so blocks the processing of subsequent AVSDirectives.

Parameters

info	The `DirectiveInfo` instance for the `AVSDirective` to process.

Implements alexaClientSDK::avsCommon::avs::CapabilityAgent.

◆ handleDirectiveImmediately()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::handleDirectiveImmediately ( std::shared_ptr< avsCommon::avs::AVSDirective > directive )

overridevirtual

Handle the action specified AVSDirective. Once this has been called the DirectiveHandler should not expect to receive further calls regarding this directive.

Note: The implementation of this method MUST be thread-safe.; The implementation of this method MUST return quickly. Failure to do so blocks the processing of subsequent AVSDirectives.; If this operation fails, an ExceptionEncountered message should be sent to AVS.

Parameters

directive The directive to handle.

Implements alexaClientSDK::avsCommon::sdkInterfaces::DirectiveHandlerInterface.

◆ hasReportableStateProperties()

bool alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::hasReportableStateProperties ( )

overridevirtual

Returns whether the provider has Reportable State Properties.

See also: https://developer.amazon.com/en-US/docs/alexa/alexa-voice-service/reportable-state-properties.html

Returns: Whether this provider has reportable state properties.

Reimplemented from alexaClientSDK::avsCommon::sdkInterfaces::StateProviderInterface.

◆ onPowerStateChanged()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::onPowerStateChanged	(	const PowerState &	powerState,
		avsCommon::sdkInterfaces::AlexaStateChangeCauseType	cause
	)

overridevirtual

Notifies the change in the power state property of the endpoint.

Parameters

powerState	The power state specified using `PowerState`.
cause	The cause for this change specified using `AlexaStateChangeCauseType`.

Implements alexaClientSDK::avsCommon::sdkInterfaces::powerController::PowerControllerObserverInterface.

◆ preHandleDirective()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::preHandleDirective ( std::shared_ptr< DirectiveInfo > info )

overridevirtual

Notification that a directive has arrived. This notification gives the DirectiveHandler a chance to prepare for handling of an AVSDirective. If an error occurs during the pre-Handling phase and that error should cancel the handling of subsequent AVSDirectives with the same DialogRequestId, the DirectiveHandler should call the setFailed method on the result instance passed in to this call.

Note: The implementation of this method MUST be thread-safe.; The implementation of this method MUST return quickly. Failure to do so blocks the processing of subsequent AVSDirectives.

Parameters

info	The `DirectiveInfo` instance for the `AVSDirective` to process.

Implements alexaClientSDK::avsCommon::avs::CapabilityAgent.

◆ provideState()

void alexaClientSDK::capabilityAgents::powerController::PowerControllerCapabilityAgent::provideState	(	const avsCommon::avs::CapabilityTag &	stateProviderName,
		const avsCommon::sdkInterfaces::ContextRequestToken	stateRequestToken
	)

overridevirtual

A request to a StateProvider to provide the state. The StateProvider should perform minimum processing and return quickly, otherwise it will block the processing of updating the states of other StateProviders. The ContextManager specifies a token which it uses to track the getContext request associated with this provideState request. The stateProviderInterface must use the same token when it updates its state via the setState call.

: The setState method MUST be called from a different thread from where the provideState method is being called from.

Parameters

stateProviderIdentifier	The identifier of the state provider.
stateRequestToken	The token to use in the `setState` call.

Note: In future versions, this method will be made pure virtual.
