Examples of com.sun.jini.discovery.DiscoveryConstraints$ConstraintReducer

com.sun.jini.discovery.DiscoveryConstraints
Utility for reducing constraints of a given type into a base set of alternatives. For each type of constraints that it reduces, this class makes the simplifying assumption that failure to reduce constraints of that type into a single (perhaps one element) set of alternatives represents a constraint conflict--i.e., that two disjoint instances of the constraint type cannot be applied to the same operation. While this restriction does not hold across all possible constraints, it is satisfied by the particular constraint types that DiscoveryConstraints handles. If this utility encounters a set of alternatives containing instances of both the type to reduce as well as other constraint types, then it ignores the instances of the other types, treating the set as if it can only be satisfied by the alternatives of the targeted type. This may in some cases cause false positives when detecting conflicts in constraints containing alternatives of mixed type; however, it should never result in false negatives.
