Detailed Description

template<typename Owner, typename... TArgs>
class ndn::util::signal::Signal< Owner, TArgs >

provides a lightweight signal / event system

To declare a signal: public: Signal<Owner, T1, T2> signalName; To connect to a signal: owner->signalName.connect(f); Multiple functions can connect to the same signal. To emit a signal from owner: this->signalName(arg1, arg2);

Template Parameters
Ownerthe signal owner class; only this class can emit the signal
TArgstypes of signal arguments
See also
signal-emit.hpp allows owner's derived classes to emit signals

Member Function Documentation

template<typename Owner , typename... TArgs>
Connection ndn::util::signal::Signal< Owner, TArgs >::connect ( const Handler handler)

connects a handler to the signal

Note
If invoked from a handler, the new handler won't receive the current emitted signal.
Warning
The handler is permitted to disconnect itself, but it must ensure its validity.

Definition at line 164 of file signal.hpp.

template<typename Owner , typename... TArgs>
Connection ndn::util::signal::Signal< Owner, TArgs >::connectSingleShot ( const Handler handler)

connects a single-shot handler to the signal

After the handler is executed once, it is automatically disconnected.
