Detailed Description

A registry for the runtime-creation of typed slots, allowing creation of type-specific VObject input parameters without knowing their types explicitly.

Usage:

if (RefPtr<TypedSlotCreator> TC = TypedSlotCreator::getTypedSlotCreator("int") )
{
RefPtr<VSlot> mySlot = TC->newSlot( ... );
}

Constructor & Destructor Documentation

◆ ~TypedSlotCreator()

Wizt::TypedSlotCreator::~TypedSlotCreator ( )

Destructor, cleans up registry.

It will be called when a type is defined in a plugin and the plugin is unloaded.

Member Function Documentation

◆ newSlot()

virtual RefPtr< VSlot > Wizt::TypedSlotCreator::newSlot	(	VSlotContainer *	that,
		const string &	name,
		const string &	InitialValue,
		bool &	Initialized,
		const RefPtr< VCreationPreferences > &	VP,
		int	ExpertLevel
	)		const

pure virtual

The virtual slot creation function.

Parameters

InitialValue	An initial value encoded as string, utilizing the VValueTrait<> template to convert into the actual type.
Initialized	Flag telling wether the slot could be initialized successfully from the given initial value. If that one is invalid, for instance it could not be parsed correctly for the final type, then the Slot will be initialized with the default constructor of the given type.

Implemented in Wizt::TypedSlot< T >::SlotCreator.

◆ registerTypedSlotCreator()

void Wizt::TypedSlotCreator::registerTypedSlotCreator	(	const type_info &	theType,
		const WeakPtr< TypedSlotCreator, TypedSlotCreator > &	who,
		const string &	name
	)

static

Add an instance of a type-specific SlotCreator to the registry.

Parameters

theType	The typeid of the value that are operated on
who	A static SlotCreator as provided by TypedSlotCreator<>::getCreator();

Referenced by Wizt::TypedSlot< T >::SlotCreator::SlotCreator().
