How to limit method parameter of enum type to certain literal?

Question

I would like to limit enum literal of particular type in parameter.

For example,

enum SomeEnum { A, B, C}
class SomeClass {
    public void doSomething(SomeEnum someEnum) { <--- Here I want to only accept A and C. 
    }
}

so as caller is typing the code,

SomeClass someclass = new SomeClass();
someclass.doSomething(); <------- java assist would say only A and C goes in here
