Detailed Description

Callback helper class with suspend support.

Unlike a normal EventWrapper, this class suspends an event on drain() and restarts it at drainResume(). The suspend operation stores the tick relative to curTick() and then deschedules the event. The resume operation schedules the event at curTick() plus the relative tick stored when the event was suspended.

DrainState BasePixelPump::PixelEvent::drain ( )

overridevirtual

Notify an object that it needs to drain its state.

If the object does not need further simulation to drain internal buffers, it returns DrainState::Drained and automatically switches to the Drained state. If the object needs more simulation, it returns DrainState::Draining and automatically enters the Draining state. Other return values are invalid.

Note: An object that has entered the Drained state can be disturbed by other objects in the system and consequently stop being drained. These perturbations are not visible in the drain state. The simulator therefore repeats the draining process until all objects return DrainState::Drained on the first call to drain().

Returns: DrainState::Drained if the object is drained at this point in time, DrainState::Draining if it needs further simulation.
