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

Owner	the signal owner class; only this class can emit the signal
TArgs	types 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.

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.
