Member Function Documentation#

clearAllOutgoingConnections()#

template<typename... Args>

void ASignal< Args >::clearAllOutgoingConnections ( ) const

inlineoverridevirtualnoexcept

Implements AAbstractSignal.

clearAllOutgoingConnectionsWith()#

template<typename... Args>

void ASignal< Args >::clearAllOutgoingConnectionsWith ( aui::no_escape< AObjectBase > receiver ) const

inlineoverridevirtualnoexcept

Parameters

receiver

object to clear connections with.

Implements AAbstractSignal.

hasOutgoingConnectionsWith()#

template<typename... Args>

bool ASignal< Args >::hasOutgoingConnectionsWith ( aui::no_escape< AObjectBase > receiver ) const

inlinenodiscardoverridevirtualnoexcept

Parameters

receiver

receiver objects to check connections with.

Returns

Whether this signal has connections with passed receiver object.

Implements AAbstractSignal.

operator bool()#

template<typename... Args>

ASignal< Args >::operator bool ( ) const

inline

It's very useful then signal argument values calculation is expensive and you do not want to calculate them if no slots connected to the signal.

Returns

true, if slot contains any connected slots, false otherwise.
