Examples of org.infinispan.distribution.DistributionManager.locate()

org.infinispan.distribution.DistributionManager.locate()
Locates a key in a cluster. The returned addresses may not be owners of the keys if a rehash happens to be in progress or is pending, so when querying these servers, invalid responses should be checked for and the next address checked accordingly. @param key key to test @return a list of addresses where the key may reside

            // since keys and values are on all nodes, lets just pick randomly
            Collections.shuffle(members);
            ownerOfKey = members.get(0);
         } else {
            // DIST mode
            List<Address> owners = dm.locate(key);
            List<Address> filtered = filterMembers(policy, owners);
            if(!filtered.isEmpty()){
               ownerOfKey = filtered.get(0);
            } else {
               ownerOfKey = owners.get(0);
