/**
* Annotation for a method that returns the Java enumeration object for a given C integer value. The
* method must be within a class annotated with {@link CEnum}. The method must be declared static,
* native, and must have exactly one parameter (the C value that is to be looked up). The method can
* have any name.
*
* The Java enumeration can have multiple values with the same C value. However, in that case one
* Java value must be selected manually using the attribute {@link CEnumConstant#includeInLookup()}.
* All but one Java values must have this attribute set to {@code false}.
