Constructor & Destructor Documentation

◆ DynamicMetaClass()

OGF::DynamicMetaClass::DynamicMetaClass	(	const std::string &	class_name,
		const std::string &	super_class_name,
		bool	is_abstract = `false`
	)

explicit

Constructs a new DynamicMetaClass.

Parameters

[in]	class_name	the C++ class name
[in]	super_class_name	the C++ name of the super class
[in]	is_abstract	indicates whether the class is abstract (e.g. with pure virtual methods) or not. Abstract classes cannot be constructed.

Member Function Documentation

◆ add_slot()

DynamicMetaSlot* OGF::DynamicMetaClass::add_slot	(	const std::string &	name,
		Callable *	action,
		const std::string &	return_type = `"void"`
	)

Creates a new slot.

Parameters

[in]	name	the name of the slot
[in]	action	the function to be called when the slot is invoked
[in]	return_type	an optional string with the return type

Returns: the created DynamicMetaSlot

one can create the arguments by calling DynamicMetaSlot::add_arg() on the returned DynamicMetaSlot.
