Detailed Description

"Callback request event" for use in Device.

Some Nodes want to perform a function on an event for each of their targets. An example is the poisson_generator which needs to draw a random number for each target. The DSSpikeEvent, DirectSendingSpikeEvent, calls sender->event_hook(*this) in its operator() function instead of calling receiver->handle(). The default implementation of Node::event_hook() just calls target->handle(DSSpikeEvent&). Any reimplementation must also execute this call. Otherwise the event will not be delivered. If needed, target->handle(DSSpikeEvent&) may be called more than once.

Note

Callback events must only be sent via static_synapse

Member Function Documentation

operator()()

void nest::DSSpikeEvent::operator() ( )

overridevirtual

Deliver the event to receiver.

This operator calls the handler for the specific event type at the receiver.

Implements nest::Event.
