Member Function Documentation

operator bool()

entt::meta_handle::operator bool ( ) const

inlineexplicitnodiscardnoexcept

Returns

This meta handle.

operator=() [2/2]

meta_handle & entt::meta_handle::operator= ( meta_handle && )

default

Default move assignment operator.

Returns

This meta handle.
