IRegion TKey, TValue  GetAll Method (ICollection TKey , IDictionary TKey, TValue , IDictionary TKey, Exception , Boolean, Object)Pivotal GemFire .NET Client Documentation
Gets values for collection of keys from the local cache or server. If value for a key is not present locally then it is requested from the java server. The value returned is not copied, so multi-threaded applications should not modify the value directly, but should use the update methods. For local region instance - this method is not applicable. Updates the LastAccessedTime and [!:CacheStatistics.HitCount] and [!:CacheStatistics.MissCount] for this region and the entry.
