Handling inheritance

Inheritance in LCL is specified when registering a class, either with the parent parameter to luaC_newclass(), or with the luaC_Class::parent member. When specifying a parent class, you should use the full module path, as you would with a require statement in Lua. Some useful utility methods are provided for working with inheritance in C code.

Note

Classes without a constructor cannot be inherited in Moonscript code. See luaC_Class::user_ctor.

• luaC_getparent will push a copy of a class’s parent onto the stack.

• luaC_super() calls the parent method with the given name. Useful for overriding methods in derived classes.

• luaC_superinit is a shorthand function to call the parent class’s init method.

• luaC_setinheritcb() sets the inheritance callback of a class.
