Struct meta_range
Synopsis
#include <src/entt/meta/range.hpp>
template<typename Type, typename Node = typename Type::node_type>
struct meta_range final
Description
Iterable range to use to iterate all types of meta objects.
- Template Parameters
Type- Type of meta objects returned.Node- Type of meta nodes iterated.
Methods
| meta_range overload | Default constructor. | |
| meta_range overload | Constructs a meta range from a given node. | |
| begin | Returns an iterator to the beginning. | |
| cbegin | Returns an iterator to the beginning. | |
| cend | Returns an iterator to the end. | |
| end | Returns an iterator to the end. |
