Member Function Documentation

assign() [1/2]

template<typename Result , typename... Args>

template<typename ClassType , typename MethodType , typename... BoundArgs>

TClosure & sf::TClosure< Result, Args >::assign	(	ClassType *	cls,
		MethodType	mtd,
		BoundArgs...	args
	)

Binds a non-static class member function to this instance.

Short for passing a std::bind(...) result the assign().
For example:

bool MyClass::method(const char* s, int i);
 
TClosure<bool, const char*, int> c2
 
c2.assign(&MyClass::method, this, std::placeholders::_1, std::placeholders::_2)

Template Parameters

ClassType	Type having the to be called method.
MethodType	Type from the passed class type.
BoundArgs	Only std::placeholders::_? enumeration values. (see std::bind)

Parameters

cls	Pointer of the class having the passed method.
mtd	Pointer to method of the given class.
args	Amount of arguments needed to call the method using std::placeholders::_? enumeration values.

Returns

Itself.
