Annotation Type AssertNonNullIfTrue

@Documented
@Retention(value=RUNTIME)
@Target(value=METHOD)
public @interface AssertNonNullIfTrue

Indicates that if the method returns true, then the value expressions are non-null.

For instance, if File.isDirectory() is true, then File.list() is non-null, and File.listFiles() is non-null. You can express this relationship as:

   @AssertNonNullIfTrue({"list()","listFiles()"})
   public boolean isDirectory() { ... }
