- All Implemented Interfaces:
Comparator<MOScope>
public class MOScopeComparator extends Object implements Comparator<MOScope>
TheMOScopeComparatorcompares two scopes with each other.Two scopes are compared by their context (if both are
MOContextScopeinstances) 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, then the scoped is deemed to be greater than the query. Otherwise, the upper bound of the scope is compared with the lower bound of the query. Scope and query are deemed to be equal if both bounds are equal and both are included. Otherwise the scope is deemed to be less than the query.- Version:

Method Detail

compare
public int compare(MOScope o1, MOScope o2)
Compares a scope with another scope or query. See also the class description how comparison is done.- Specified by:
comparein interfaceComparator<MOScope>- Parameters:
o1- a MOScope instance.o2- a MOScope instance.- Returns:
- an integer less than zero if
o1is less thano2and zero if both values are deemed to be equal and a value greater than zero ifo1is greater thano2.

isQueryContextMatching
public static boolean isQueryContextMatching(MOQuery a, MOScope b)
Indicates whether the given query's context matches the context of the given scope.- Parameters:
a- a MOQuery instance.b- another MOScope instance.- Returns:
trueif the query's context isnullor if both contexts match or if the context ofscopeis the empty string.- Since:
- 2.0.2
