question: public static boolean isAccessorPair ( TMember member , TMember member2 ) { return ( member instanceof TGetter && member2 instanceof TSetter ) || ( member instanceof TSetter && member2 instanceof TGetter ) ; }
target:  Returns true if one of the members is a getter and the other one is a setter. No further validation such as name or owner comparison is done as this is expected to be done in the client already.
