Detailed Description

Opaque pointers to instances of any type.

A handle doesn't perform copies and isn't responsible for the contained object. It doesn't prolong the lifetime of the pointed instance. Users are responsible for ensuring that the target object remains alive for the entire interval of use of the handle.

Constructor & Destructor Documentation

meta_handle() [1/3]

entt::meta_handle::meta_handle ( )

inline

Default constructor.

meta_handle() [2/3]

entt::meta_handle::meta_handle ( meta_any &  any )

inline

Constructs a meta handle from a meta any object.

Parameters

any	A reference to an object to use to initialize the handle.

meta_handle() [3/3]

template<typename Type , typename = std::enable_if_t<!std::is_same_v<std::remove_cv_t<std::remove_reference_t<Type>>, meta_handle>>>

entt::meta_handle::meta_handle ( Type &  obj )

inline

Constructs a meta handle from a given instance.

Template Parameters

Type	Type of object to use to initialize the handle.

Parameters

obj	A reference to an object to use to initialize the handle.
