Detailed Description

Defines the event aggregator interface type.

Constructor & Destructor Documentation

EventAggregator() [1/3]

hgps::EventAggregator::EventAggregator ( )

default

Initialises a new instance of the EventAggregator class.

EventAggregator() [2/3]

hgps::EventAggregator::EventAggregator ( EventAggregator &&  other )

default

Constructs the EventAggregator using move semantics.

Parameters

other

The other EventAggregator instance to move

EventAggregator() [3/3]

hgps::EventAggregator::EventAggregator ( const EventAggregator &  )

delete

~EventAggregator()

virtual hgps::EventAggregator::~EventAggregator ( )

virtualdefault

Destroys a EventAggregator instance.

Member Function Documentation

operator=() [1/2]

EventAggregator& hgps::EventAggregator::operator= ( const EventAggregator &  )

delete

operator=() [2/2]

EventAggregator& hgps::EventAggregator::operator= ( EventAggregator &&  other )

default

Replaces the EventAggregator contents with the other using move semantics.

Parameters

other

The other EventAggregator instance to move

Returns

This instance

publish()

virtual void hgps::EventAggregator::publish ( std::unique_ptr< EventMessage >  message )

pure virtual

Publishes a message to all subscribers synchronous.

Parameters

message

The new message instance

Implemented in hgps::DefaultEventBus.

publish_async()

virtual void hgps::EventAggregator::publish_async ( std::unique_ptr< EventMessage >  message )

pure virtual

Publishes a message to all subscribers asynchronous.

Parameters

message

The new message instance

Implemented in hgps::DefaultEventBus.

subscribe()

virtual std::unique_ptr<EventSubscriber> hgps::EventAggregator::subscribe ( EventType  event_id, std::function< void(std::shared_ptr< EventMessage > message)> &&  handler  )

pure virtual

Subscribes a handler function to an event type identifier.

Parameters

event_id	The event type to subscribe
handler	The event handler function to register

Returns

The event subscriber instance

Implemented in hgps::DefaultEventBus.

Here is the caller graph for this function:

unsubscribe()

virtual bool hgps::EventAggregator::unsubscribe ( const EventSubscriber &  subscriber )

pure virtual

Unsubscribes from an event notification.

Parameters

subscriber

The event subscriber instance

Returns

true if the operation succeeded; otherwise, false

Implemented in hgps::DefaultEventBus.
