Member Function Documentation

takeQueue()

virtual void Vkm::Engine::IBus::takeQueue ( )

pure virtual

Set this bus's queued events aside, ready to be delivered.

Split from deliver so every bus is drained before any listener runs; otherwise a listener's enqueue would go out this flush or the next depending on bus order.

Implemented in Vkm::Engine::Bus< EventT >.

hasListeners()

virtual bool Vkm::Engine::IBus::hasListeners ( ) const

pure virtual

Whether anything is still listening on this bus.

See EventBus::dropIdleBuses().

Returns

True while at least one live listener remains.

Implemented in Vkm::Engine::Bus< EventT >.
