Description
hasmetatable is part of the Metatables library. Metatable helpers operate below normal Lua protection: they read raw metatables, replace metamethods and inspect namecalls.
The call is a predicate: it inspects the current state and returns a boolean without modifying anything.
Example
print(hasmetatable(setmetatable({}, {}))) -- trueNotes
- Metatable changes are applied directly to the live object.
