Thank you for your quick reply.
The spec says that "If A or B is an enum, coerce both A and B to enum, apply
operator".
Does't it simply mean that both A and B must be coercible to enums. instead
of if A is an enum then B must be an enum of type A, or vice versa.
in the coerceToEnum method I would return the object if it is an enum
(whatever its type is):
public final static Enum<?> coerceToEnum(final Object obj, Class type) {
if (obj == null || "".equals(obj)) {
return null;
}
if(obj.getClass().isEnum()){
return (Enum<?>)obj;
}
...
}
Like the original creator of this post, I have a series of enums of
different types that implement a common interface. I need to be able to
compare them and I don't want to have to translate them to Strings.
