Detailed Description

Opaque wrapper for meta base classes.

Constructor & Destructor Documentation

meta_base()

entt::meta_base::meta_base ( const node_type *  curr = nullptr )

inline

Constructs an instance from a given node.

Parameters

curr	The underlying node with which to construct the instance.

Member Function Documentation

cast()

const void* entt::meta_base::cast ( const void *  instance ) const

inline

Casts an instance from a parent type to a base type.

Parameters

instance

The instance to cast.

Returns

An opaque pointer to the base type.

operator bool()

entt::meta_base::operator bool ( ) const

inlineexplicit

Returns true if a meta object is valid, false otherwise.

Returns

True if the meta object is valid, false otherwise.

parent()

meta_type entt::meta_base::parent ( ) const

inline

Returns the meta type to which a meta object belongs.

Returns

The meta type to which the meta object belongs.

type()

meta_type entt::meta_base::type ( ) const

inline

Returns the meta type of the underlying object.

Returns

The meta type of the underlying object, if any.
