Member Typedef Documentation

typedef std::map<boost::shared_ptr<OnDemandProducer>, std::vector<OnDemandMessage> > fesa::AbstractServerAction::ODProducerToODMessagesMap

protected

Maps on demand producers to vectors of on demand messages.

Constructor & Destructor Documentation

fesa::AbstractServerAction::AbstractServerAction	(	const ServerActionConfig &	actionConfig,
		const AbstractServiceLocator *	serviceLocator,
		const std::map< std::string, const AbstractServiceLocator * > &	serviceLocatorRelatedClasses
	)

Parameters

actionConfig which contains all the attributes to create the action

Member Function Documentation

void fesa::AbstractServerAction::checkInvalidatingFields	(	AbstractDevice *	device,
		const MultiplexingContext *	context
	)		const

protected

Throws if any of the disabling fault-fields of the action is raised.

void fesa::AbstractServerAction::clearPendingOnDemandMessages ( )

protected

Removes all messages from the pending on demand messages.

virtual std::auto_ptr<PropertyData> fesa::AbstractServerAction::executeGet	(	RequestEvent *	event,
		AbstractDevice &	device,
		const cmw::data::Data &	filter
	)

pure virtual

This method is called by a Property::get() and calls the user's get-server-action code. It returns a PropertyData object whose ownership is transferred to the caller.

Parameters

device	the device to use
event	object containing the context
filter	optional filter data, may be empty

Returns: a PropertyData object containing the result of the get action.

virtual void fesa::AbstractServerAction::executeSet	(	RequestEvent *	event,
		AbstractDevice &	device,
		const PropertyData &	propertyData,
		const cmw::data::Data &	filter
	)

pure virtual

This method is called by a Property::set() and calls the user's set-server-action code.

Parameters

device	the device to use
event	object containing the context
propertyData	a container object filled with the data to set
filter	optional filter data, may be empty

bool fesa::AbstractServerAction::hasDataChanged	(	const RequestEvent &	event,
		AbstractDevice &	device,
		const cmw::data::Data &	filter
	)		const

virtual

Check if the data published by this server action's property changed The check will be done only during a subscription The default implementation always returns 'true'. It can be overridden by a FESA class developer.

Parameters

event	The request event that triggered this server action
device	The device this server action's property belongs to
filter	The data filter

Returns: 'true' if the data published by the property changed, 'false' otherwise

bool fesa::AbstractServerAction::isPartialSetAllowed ( )

virtual

Returns: true if the action supports partial sets

bool fesa::AbstractServerAction::needFilter ( )

virtual

Returns: true if the action needs a filter

void fesa::AbstractServerAction::notify	(	boost::shared_ptr< MultiplexingContext > &	context,
		AbstractDevice &	device,
		RequestType::RequestType	reqType = `RequestType::GET`
	)

protected

this method notifies the properties in the server action

Parameters

transactionCtxt	the multiplexing context to be notified
device	which triggers the notification

void fesa::AbstractServerAction::printConfig ( FesaStream & fesaStream )

virtual

this method prints the action configuration into the stream passed by argument

Parameters

configStream in which the information will be printed

void fesa::AbstractServerAction::registerAllAutomaticallyTriggeredOnDemandEventSources	(	const MultiplexingContext *	context,
		const char *	payload,
		std::size_t	payloadSize,
		uint32_t	msgPrio = `DEFAULT_ON_DEMAND_MESSAGE_PRIO`
	)

protected

Registers an on demand message for every automatically triggered on demand event source. They are sent by sendPendingOnDemandMessages().

void fesa::AbstractServerAction::sendPendingOnDemandMessages ( uint32_t synchronizationId )

protected

Sends pending On Demand messages. Sends all the messages contained in pendingOnDemandMessages_, and empties the vector.

Parameters

synchronizationId the synchronization id to wait for before executing the event

void fesa::AbstractServerAction::triggerOnDemandEventSource	(	const std::string &	sourceName,
		const MultiplexingContext *	context,
		const char *	payload,
		std::size_t	payloadSize,
		uint32_t	msgPrio = `DEFAULT_ON_DEMAND_MESSAGE_PRIO`
	)

This implementation delays the sending of the on demand event till after the execution of the action. This implementation delays the sending of the on demand event till after the execution of the action.

void fesa::AbstractServerAction::triggerOnDemandEventSource	(	const std::string &	sourceName,
		const MultiplexingContext *	context,
		uint32_t	msgPrio = `DEFAULT_ON_DEMAND_MESSAGE_PRIO`
	)

This implementation delays the sending of the on demand event till after the execution of the action. This method is only here because of c++ overload resolution: even though it is virtual in the base class (AbstractAction), it needs to be present here to be visible to child classes. It does nothing but call the base implementation (which in turn call the version with the payload parameters).
