Detailed Description

Factory singleton for creating DataComponents from string IDs.

Every DataComponent implements the id() method returning a unique string identifier for that specific type of DataComponent. DataComponents have to be registered with DataComponentFactory using this string ID and a factory method for instantiating a DataComponent of such type. During registration DataComponentFactory ensures the uniqueness of the registered DataComponents and otherwise raises an assertion/logs a warning.

Member Function Documentation

◆ registerComponent()

void registerComponent	(	const std::string &	id,
		FactoryMethod	factoryMethod )

Registers a DataComponent with the DataComponentFactory.

Note: The string IDs of DataComponents have to be unique. If you register an ID a second time, the previously registered factory method will be overwritten. Debug builds will also raise an assertion.

Parameters

id	Unique string ID for the DataComponent to register.
factoryMethod	Method to use for instantiating the DataComponent to register.

◆ createComponent()

std::unique_ptr< DataComponentBase > createComponent	(	const std::string &	id,
		const Properties *	p = nullptr )

Instantiates a DataComponent specified by the given ID.

Parameters

id	Unique ID of the DataComponent to create.
p	Optional pointer to a Properties object. If not 0, it will used to configure the newly created DataComponent.
