Returns: true if receiver is subcribed; false otherwise.

◆ hasSubscriber() [2/3]

template<typename S >

bool CppMate::Signal< S >::hasSubscriber ( Function subscriber ) const

inline

Indicates that the receiver is already subscribed to the signal.

Parameters

subscriber the receiver function.

Returns: true if receiver is subcribed; false otherwise.

◆ hasSubscriber() [3/3]

template<typename S >

template<typename T >

bool CppMate::Signal< S >::hasSubscriber	(	std::shared_ptr< T >	instance,
		void(T::*)(const S &)	method
