Gets a handle to the cache service. Although there is only one actual
cache, an application may make as many MemcacheService instances
as it finds convenient.
If using multiple instances, note that the error handler established with
MemcacheService#setErrorHandler(ErrorHandler) is specific to each
instance.
Gets a handle to the cache service, forcing use of specific namespace.
The method returns MemcacheService
similar to the one returned by
MemcacheServiceFactory#getMemcacheService()
but it will use specified namespace for all operations.
if not null forces the use of namespace
for all operations in MemcacheService . If namespace is
null - created MemcacheService will use current namespace
provided by com.google.appengine.api.NamespaceManager#get().
