Attributes, Specifiers, and Effects

Specifiers

The following specifiers determine how you can interact with OnBegin in your programs. For the complete list of specifiers, see the Specifiers Page.

Specifier Meaning
public The identifier is universally accessible. You can use this on modules, classes, interfaces, structs, enums, methods, and data.
native_callable Indicates that an instance method is both native (implemented in C++) and may be called by other C++ code. You can see this specifier used on an instance method. This specifier doesn’t propagate to subclasses and so you don’t need to add it to a definition when overriding a method that has this specifier.

Effects
