Detailed Description

CapabilitiesDelegate provides an implementation of the CapabilitiesDelegateInterface. It allows clients to register capabilities implemented by agents and publish them so that Alexa is aware of the device's capabilities.

Member Function Documentation

◆ addCapabilitiesObserver()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::addCapabilitiesObserver ( std::shared_ptr< avsCommon::sdkInterfaces::CapabilitiesObserverInterface > observer )

overridevirtual

Specify an object to observe changes to the state of this CapabilitiesDelegate. During the call to this setter the observers onCapabilitiesStateChange() method will be called back with the current capabilities state.

Parameters

observer The object to observe the state of this CapabilitiesDelegate.

Implements alexaClientSDK::avsCommon::sdkInterfaces::CapabilitiesDelegateInterface.

◆ addDiscoveryEventSender()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::addDiscoveryEventSender ( const std::shared_ptr< DiscoveryEventSenderInterface > & discoveryEventSender )

Adds the event sender used to send Discovery events.

◆ addOrUpdateEndpoint()

bool alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::addOrUpdateEndpoint	(	const avsCommon::avs::AVSDiscoveryEndpointAttributes &	endpointAttributes,
		const std::vector< avsCommon::avs::CapabilityConfiguration > &	capabilities
	)

override

◆ clearData()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::clearData ( )

overridevirtual

Reset any internal state that may be associated with a particular user.

Warning: Object must succeed in deleting any customer data.; This method is called while CustomerDataManager is in a locked state. Do not call or wait for any CustomerDataManager operation.

Implements alexaClientSDK::registrationManager::CustomerDataHandler.

◆ create()

std::shared_ptr< CapabilitiesDelegate > alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::create	(	const std::shared_ptr< avsCommon::sdkInterfaces::AuthDelegateInterface > &	authDelegate,
		const std::shared_ptr< storage::CapabilitiesDelegateStorageInterface > &	storage,
		const std::shared_ptr< registrationManager::CustomerDataManager > &	customerDataManager
	)

static

Create an CapabilitiesDelegate.

Parameters

authDelegate	The auth delegate instance needed for CapabilitiesDelegate.
storage	The storage instance needed for CapabilitiesDelegate.
customerDataManager	Object that will track the CustomerDataHandler.

Returns: If successful, returns a new CapabilitiesDelegate, otherwise nullptr.

◆ createPostConnectOperation()

std::shared_ptr< PostConnectOperationInterface > alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::createPostConnectOperation ( )

overridevirtual

Creates a post connect operation instance.

Returns: a new instance of the PostConnectOperationInterface.

We track the original pending endpoints in order to notify observers of their registration, even if CapabilitiesDelegate does not need to actually send the events since they are already registered with AVS.

The endpoints that need to be sent to AVS.

If any endpoints were in-flight at the time of creating a post-connect operation, move them back to pending to be re-filtered and sent as part of the post-connect operation.

If the database is empty, send any cached endpoints as part of this post-connect operation.

If the stored endpoint is pending deletion, do not include it in the addOrUpdateReport.

If the registered endpoint does not have a pending change, add the stored configuration to the addOrUpdateReport. Otherwise, prefer the pending change as it's more recent.

Move endpoints from pending to in-flight, since they will now be sent.

Sometimes pending add/update endpoints do not need to be sent to AVS as they are already stored and registered with AVS. In this case, we should still notify observers that registration succeeded even though no Discovery event was sent. This logic is not required for pending delete endpoints, since calls to CapabilitiesDelegate.deleteEndpoint fail when the endpoint is not already cached with CapabilitiesDelegate.

Implements alexaClientSDK::avsCommon::sdkInterfaces::PostConnectOperationProviderInterface.

◆ deleteEndpoint()

bool alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::deleteEndpoint	(	const avsCommon::avs::AVSDiscoveryEndpointAttributes &	endpointAttributes,
		const std::vector< avsCommon::avs::CapabilityConfiguration > &	capabilities
	)

override

◆ doShutdown()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::doShutdown ( )

overridevirtual

Prepares/enables this object to be deleted. This should be the last function called on this object prior to deleting (or resetting) its shared_ptr.

Warning

Attempting to call functions on this object after calling shutdown() can result in undefined behavior.
Neglecting to call shutdown() on this object can result in resource leaks or other undefined behavior.

Implements alexaClientSDK::avsCommon::utils::RequiresShutdown.

◆ invalidateCapabilities()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::invalidateCapabilities ( )

overridevirtual

Invalidates the capabilities reported to the AVS last. Capabilities information should be rebuilt and reported to the AVS during the next synchronization.

Implements alexaClientSDK::avsCommon::sdkInterfaces::CapabilitiesDelegateInterface.

◆ onAlexaEventProcessedReceived()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::onAlexaEventProcessedReceived ( const std::string & eventCorrelationToken )

overridevirtual

This function is called whenever an Alexa.EventProcessed directive is received.

Parameters

eventCorrelationToken The EventCorrelationToken string.

Implements alexaClientSDK::avsCommon::sdkInterfaces::AlexaEventProcessedObserverInterface.

◆ onAVSGatewayChanged()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::onAVSGatewayChanged ( const std::string & avsGateway )

overridevirtual

Observer method to be called when the AVS Gateway is changed.

Parameters

avsGateway The AVS Gateway the device should be connected to.

Implements alexaClientSDK::avsCommon::sdkInterfaces::AVSGatewayObserverInterface.

◆ onConnectionStatusChanged()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::onConnectionStatusChanged	(	const Status	status,
		const ChangedReason	reason
	)

overridevirtual

Called when the AVS connection state changes.

Parameters

status	The current connection status.
reason	The reason the status change occurred.

If newly connected, send Discovery events for any endpoints that may have been added or deleted during the post-connect stage.

Implements alexaClientSDK::avsCommon::sdkInterfaces::ConnectionStatusObserverInterface.

◆ onDiscoveryCompleted()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::onDiscoveryCompleted	(	const std::unordered_map< std::string, std::string > &	addOrUpdateReportEndpoints,
		const std::unordered_map< std::string, std::string > &	deleteReportEndpoints
	)

overridevirtual

This method will be called when the discovery event has completed successfully.

Note: : This method will be called from PostConnectCapabilitiesPublisher 's execution thread and should return immediately.; : This method will be called by the PostConnectCapabilitiesPublisher to report the success state when ALL of the the discovery events are sent.

Parameters

addOrUpdateReportEndpoints	The map of addOrUpdateReport endpoints sent in the discovery events.
deleteReportEndpoints	The map of deleteReport endpoints sent in the discovery events.

Implements alexaClientSDK::capabilitiesDelegate::DiscoveryStatusObserverInterface.

◆ onDiscoveryFailure()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::onDiscoveryFailure ( avsCommon::sdkInterfaces::MessageRequestObserverInterface::Status status )

overridevirtual

This method will be called when the discovery event has failed.

Parameters

status The MessageRequestObserverInterface::Status indicating the HTTP error encountered.

Implements alexaClientSDK::capabilitiesDelegate::DiscoveryStatusObserverInterface.

◆ removeCapabilitiesObserver()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::removeCapabilitiesObserver ( std::shared_ptr< avsCommon::sdkInterfaces::CapabilitiesObserverInterface > observer )

overridevirtual

Remove an observer.

Parameters

observer The observer to remove.

Implements alexaClientSDK::avsCommon::sdkInterfaces::CapabilitiesDelegateInterface.

◆ setMessageSender()

void alexaClientSDK::capabilitiesDelegate::CapabilitiesDelegate::setMessageSender ( const std::shared_ptr< avsCommon::sdkInterfaces::MessageSenderInterface > & messageSender )

overridevirtual

Set the message sender to use for sending Discovery events to AVS when connected.

Parameters

messageSender The message sender.

Implements alexaClientSDK::avsCommon::sdkInterfaces::CapabilitiesDelegateInterface.
