public class MOScopeComparator
extends java.lang.Object
implements java.util.Comparator

The MOScopeComparator compares two scopes with each other or it compares a scope and a MOQuery with each other.

Two scopes are compared by their context (if both are MOContextScope instances) first and then by their lower bound.

A scope is compared with a query by comparing the scope with the queries scope and then if both are deemed to be equal, the upper bound of the scope is checked. If it is unbounded (upper bound is null
