virtual Y2Function* Y2Namespace::createFunctionCall	(	const string	name,
		constFunctionTypePtr	type
	)			[pure virtual]

Creates a function call instance, which can be used to call a function from this namespace. The object is NOT owned anymore by this instance, the caller can (and should) delete it.

Parameters:

	name	name of the required function
	type	the type of the function (needed for overloading)

Returns:

an object, that can be used to call the function, or NULL on error

Implemented in YBlock, and Y2SystemNamespace.
