Public Methods

IRegistry

IRegistry() = default

Defaulted constructor.

createInstance

virtual inline

virtual inline ItemT * createInstance(const std::string & s)

Creates and returns a new heap-allocated instance of the type registered under key s.

Parameters

• s The registration key (type name).

Returns

Pointer to the new instance, or nullptr if s is not registered.

registerType

inline

template<typename T> inline void registerType(const std::string & s)

Registers type T under the given key s. Emits TypeRegistered. Subsequent calls to createInstance(s) will return new T().

Parameters

• T Concrete type to register; must be default-constructible and derive from ItemT.

Parameters

• s Registration key (type name).

unregisterType

virtual inline

virtual inline void unregisterType(const std::string & s)

Removes the type registered under key s. Emits TypeUnregistered. Does nothing if s is not registered.

Parameters

• s Registration key to remove.

types

const inline

inline TypeMap types() const

Returns a copy of the current type map.

Returns

Map of registration keys to factory function pointers.
