Attributes, Specifiers, and Effects
Specifiers
The following specifiers determine how you can interact with IsInScene 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 |
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. |
final |
You can only use the final specifier on classes and members of classes. When a class has the final specifier, you cannot create a subclass of the class. When a field has the final specifier, you cannot override the field in a subclass. When a method has the final specifier, you cannot override the method in a subclass. |
Effects
The following effects determine how IsInScene behaves in your programs. For the complete list of effects, see the Effect Specifers section of the Specifiers Page.
| Effect | Meaning |
|---|---|
reads |
This effect indicates that the same inputs to the function may not always produce the same output. The behavior depends on factors external to the specified inputs, such as memory or the containing package version. |
computes |
This effect requires that the function has no side effects, and is not guaranteed to complete. There's an unchecked requirement that the function, when provided with the same arguments, produces the same result. Any function that doesn't have the native specifier that would otherwise have the converges effect is a good example of using the computes effect. |
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. |
