Attributes, Specifiers, and Effects
Specifiers
The following specifiers determine how you can interact with OnStarted in your programs. For the complete list of specifiers, see the Specifiers Page.
| Specifier | Meaning |
|---|---|
protected |
The identifier is only accessible in the current class and any subtypes. You can use this on classes, interfaces, structs, enums, non-module methods, and data. |
native |
Indicates that the definition details of the element are implemented in C++. Verse definitions with the native specifier auto-generate C++ definitions that a developer can then fill out its implementation. You can use this specifier on classes, interfaces, 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
The following effects determine how OnStarted behaves in your programs. For the complete list of effects, see the Effect Specifers section of the Specifiers Page.
| Effect | Meaning |
|---|---|
transacts |
This effect indicates that any actions performed by the function can be rolled back. The transacts effect is required any time a mutable variable (var) is written. You'll be notified when you compile your code if the transacts effect was added to a function that can't be rolled back. Note that this check is not done for functions with the native specifier. |
decides |
Indicates that the function can fail, and that calling this function is a failable expression. Function definitions with the decides effect must also have the transacts effect, which means the actions performed by this function can be rolled back (as if the actions were never performed), if there's a failure anywhere in the function. |
