  @Nullable public static RegionResolver compose(@Nullable Iterable<RegionResolver> regionResolvers)

  Factory method used to compose an Iterable collection of RegionResolvers in a composition.

  Parameters:

  regionResolvers - Iterable collection of RegionResolvers to compose; may be null.

  Returns:

• compose

  @Nullable public static RegionResolver compose(@Nullable RegionResolver one, @Nullable RegionResolver two)

  Composes two RegionResolvers in a composition.

  Parameters:

  one - first RegionResolver in the composition.

  two - second RegionResolver in the composition.

  Returns:

  a ComposableRegionResolver composed of the RegionResolver arguments. Returns the first RegionResolver if the second is null. Returns the second RegionResolver if the first is null. Returns null if both RegionResolver arguments are null.

• getRegionResolverOne

  @NonNull protected RegionResolver getRegionResolverOne()

  Returns a reference to the first, non-null, configured RegionResolver in the composition.

  Returns:

  a reference to the first RegionResolver in the composition.

• getRegionResolverTwo

  @NonNull protected RegionResolver getRegionResolverTwo()

  Returns a reference to the second, non-null, configured RegionResolver in the composition.

• doResolve

  @Nullable protected <K, V> org.apache.geode.cache.Region<K,V> doResolve(@Nullable String regionName)

  Resolves the first non-null reference to cache Region identified by the given name, handling any Exceptions throwing by the composed RegionResolvers, such as a RegionDestroyedException. This method may ultimately still result in a thrown Exception, but it will make a best effort to exhaustively consult all composed RegionResolvers.

  Specified by:

  doResolve in class AbstractCachingRegionResolver

  Type Parameters:

  K - type of the Region key.

  V - type of the Region value.

  Parameters:

  regionName - name of the Region to resolve.

  Returns:

  the first, resolved reference to a cache Region identified by the given name.
