    Description

      {{ public RegionState getRegionState(final String encodedRegionName) {
      // TODO: Need a map <encodedName, ...> but it is just dispatch merge...
      for (RegionStateNode node: regionsMap.values()) {
      if (node.getRegionInfo().getEncodedName().equals(encodedRegionName))

      { return node.toRegionState(); }

      }
      return null;
      }}}

      It is not used much so making it trivial.
