protectedvirtual

A sub class must implement this for a call to a single receiver.

This methods gets the signal in a folded representation, it has to unfold it, and pass it to a single receiver. For boolean signals, the return value of the receiver must be returned, for void signals, the return value is discarded.

Implements lout::signal::Emitter.
