Inherited Members
Assembly: Alachisoft.NCache.Runtime.dll
Syntax
[Serializable]
public class KeyDependency : CacheDependency, IDisposable, IBinaryProtocolSerializable
Remarks

Whenever an item is added in cache with Key Dependency, then any changes in the other item results in removal of the dependent item. The key should already exist in cache on which an item depends on. An item can depend on multiple keys. Cyclic dependency is however not supported.
