Annotation Type CFComment

@Retention(value=SOURCE)
public @interface CFComment

This annotation is for comments related to the Checker Framework.

Using @CFComment makes it easy to find Checker-Framework-related comments, and to copy those comments from one version of a codebase to another (using the Annotation File Utilities).

Here is an example:

  @CFComment("interning: factory methods guarantee that all elements are interned")
  public class MyClass {
    @CFComment({"nullness: non-null return type is more specific than in superclass",
                "signedness: comment related to Signedness type system"})
    public String myMethod(){ ... }
 }
 

As a matter of style, programmers should use this annotation on the most deeply nested element to which the comment applies (e.g., local variable rather than method, and method rather than class).

Comments about Checker Framework annotations. The text is not interpreted by the Checker Framework.

If you prefix each comment by the name of the type system, the comments are easier to understand and search for.
