cangjie-reflect-and-annotation

Cangjie controls integer overflow using annotations like `@OverflowThrowing`, `@OverflowWrapping`, and `@OverflowSaturating`. Applying these ensures critical arithmetic operations handle overflow by throwing errors, wrapping values, or saturating bounds.

Cangjie reflection uses the `TypeInfo` API to inspect and interact with types, members, and functions at runtime. You retrieve type metadata through `TypeInfo` to facilitate dynamic runtime introspection and manage program structures.

Yes, Cangjie allows defining custom annotations using the `@Annotation` system. You can apply type-safe, declarative metadata to classes or methods, enabling code generation tools to identify and process specific targets dynamically.

`@OverflowThrowing` halts execution by throwing an error upon integer overflow, preventing silent data corruption. `@OverflowSaturating` clamps the arithmetic result to the maximum or minimum integer bounds instead of throwing or wrapping.

Use the Cangjie `TypeInfo` API when your program requires dynamic behavior based on type structures, such as retrieving custom annotations at runtime or inspecting class members to automate metadata-driven logic.

Yes, Cangjie provides built-in annotations for testing frameworks and integer overflow control. Annotations like `@OverflowWrapping` specifically modify arithmetic operators to wrap values upon exceeding integer limits.
