op	A valid function object.

◆ construct()

template<typename... Args>

meta_any entt::meta_type::construct ( Args &&... args ) const

inline

Creates an instance of the underlying type, if possible.

To create a valid instance, the types of the parameters must coincide exactly with those required by the underlying meta constructor. Otherwise, an empty and then invalid container is returned.

Template Parameters

Args	Types of arguments to use to construct the instance.

Parameters

Returns: A meta any containing the new instance, if any.

◆ destroy()
