Provides a base class that represents a ChangeMonitor type that can be implemented in order to monitor changes to cache entries.
Assembly: System.Runtime.Caching (in System.Runtime.Caching.dll)
Thetype exposes the following members.
|CacheKeys||Gets a collection of cache keys that are monitored for changes.|
|HasChanged||Gets a value that indicates that the state that is monitored by the ChangeMonitor class has changed. (Inherited from ChangeMonitor.)|
|IsDisposed||Gets a value that indicates that the derived instance of a ChangeMonitor class is disposed. (Inherited from ChangeMonitor.)|
|LastModified||Gets a value that indicates the latest time (in UTC time) that the monitored cache entry was changed.|
|RegionName||Gets the name of a region of the cache.|
|UniqueId||Gets a value that represents the ChangeMonitor class instance. (Inherited from ChangeMonitor.)|
|Dispose()||Releases all resources that are used by the current instance of the ChangeMonitor class. (Inherited from ChangeMonitor.)|
|Dispose(Boolean)||Releases all managed and unmanaged resources and any references to the ChangeMonitor instance. This overload must be implemented by derived change-monitor classes. (Inherited from ChangeMonitor.)|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|InitializationComplete||Called from the constructor of derived classes to indicate that initialization is finished. (Inherited from ChangeMonitor.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|NotifyOnChanged||Called by Cache implementers to register a callback and notify an ObjectCache instance through the OnChangedCallback delegate when a dependency has changed. (Inherited from ChangeMonitor.)|
|OnChanged||Called by derived classes to raise the event when a dependency changes. (Inherited from ChangeMonitor.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
The class provides abstract, read-only properties that can be implemented for monitoring cache entries. This class is used when a cache implementation has to monitor changes to entries in its own cache. For caches that are ObjectCache cache implementations, an instance of the type is returned by the CreateCacheEntryChangeMonitor(IEnumerable<String>, String) method.Notes to Inheritors
For information about the inheritance contract that must be followed, see the information for inheritors in the ChangeMonitor class overview.
