Detailed Description

Factory singleton for creating GlObject from string IDs.

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

Public Types
using	CompatibilityFunction = std::function<bool(const Data* data, const std::vector<GlObject*>& objects)>
	Alias for a function which checks if the corresponding FactoryFunction is compatible with the given input.

using	FactoryFunctionSimple = std::function<std::unique_ptr<GlObject>()>
	Alias for a GlObjectFactory factory function creating a specific GlObject.

using	FactoryFunction = std::function<std::unique_ptr<GlObject>(const Data* data, const std::vector<GlObject*>& objects)>
	Alias for a GlObjectFactory factory function creating a specific GlObject which can depend on Data and can wrap other GlObjects.

Public Member Functions
void	registerObject (const std::string &id, FactoryFunction factoryFunction, CompatibilityFunction factoryCompatibilityFunction)
	Registers a GlObject with the GlObjectFactory.

void	registerObject (const std::string &id, FactoryFunctionSimple factoryFunction)
	Registers a GlObject with the GlObjectFactory which does not require Data of GlObjects.

bool	canCreateObject (const std::string &id, const Data data=nullptr, const std::vector< GlObject > &objects={})
	Test if a GlObject can be constructed with the given ID and the provided arguments.

std::unique_ptr< GlObject >	createObject (const std::string &id, const Properties p=nullptr, const Data data=nullptr, const std::vector< GlObject * > &objects={})
	Instantiates a GlObject specified by the given ID.

Member Function Documentation

◆ registerObject() [1/2]

void registerObject	(	const std::string &	id,
		FactoryFunction	factoryFunction,
		CompatibilityFunction	factoryCompatibilityFunction )

Registers a GlObject with the GlObjectFactory.

Note: The string IDs of GlObjects 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 GlObject to register.
factoryFunction	Method to use for instantiating the GlObject to register which takes reference data and potential objects to wrap.
factoryCompatibilityFunction	Method to use for checking if the GlObject can be created with given data and potential objects to wrap.

◆ registerObject() [2/2]

void registerObject	(	const std::string &	id,
		FactoryFunctionSimple	factoryFunction )

Registers a GlObject with the GlObjectFactory which does not require Data of GlObjects.

Note: The string IDs of GlObjects 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 GlObject to register.
factoryFunction	Method to use for instantiating the GlObject to register.

◆ canCreateObject()

bool canCreateObject	(	const std::string &	id,
		const Data *	data = nullptr,
		const std::vector< GlObject * > &	objects = {} )

Test if a GlObject can be constructed with the given ID and the provided arguments.

Parameters

id	Unique ID of the GlObject to create.
p	Optional pointer to a Properties object. If not 0, it will used to configure the newly created GlObject.
data	Data on which the GlObject relies (optional).
objects	GlObjects on which the GlObject relies (optional).

◆ createObject()

std::unique_ptr< GlObject > createObject	(	const std::string &	id,
		const Properties *	p = nullptr,
		const Data *	data = nullptr,
		const std::vector< GlObject * > &	objects = {} )

Instantiates a GlObject specified by the given ID.

Parameters

id	Unique ID of the GlObject to create.
p	Optional pointer to a Properties object. If not 0, it will used to configure the newly created GlObject.
data	Data on which the GlObject relies (optional).
objects	GlObjects on which the GlObject relies (optional).
