CacheEntryChangeMonitor Class

.NET Framework (current version)
 

Provides a base class that represents a ChangeMonitor type that can be implemented in order to monitor changes to cache entries.

Namespace:   System.Runtime.Caching
Assembly:  System.Runtime.Caching (in System.Runtime.Caching.dll)

System::Object
  System.Runtime.Caching::ChangeMonitor
    System.Runtime.Caching::CacheEntryChangeMonitor

public ref class CacheEntryChangeMonitor abstract : ChangeMonitor

NameDescription
System_CAPS_protmethodCacheEntryChangeMonitor()

Initializes a new instance of the CacheEntryChangeMonitor class. This constructor is called from constructors in derived classes to initialize the base class.

NameDescription
System_CAPS_pubpropertyCacheKeys

Gets a collection of cache keys that are monitored for changes.

System_CAPS_pubpropertyHasChanged

Gets a value that indicates that the state that is monitored by the ChangeMonitor class has changed.(Inherited from ChangeMonitor.)

System_CAPS_pubpropertyIsDisposed

Gets a value that indicates that the derived instance of a ChangeMonitor class is disposed.(Inherited from ChangeMonitor.)

System_CAPS_pubpropertyLastModified

Gets a value that indicates the latest time (in UTC time) that the monitored cache entry was changed.

System_CAPS_pubpropertyRegionName

Gets the name of a region of the cache.

System_CAPS_pubpropertyUniqueId

Gets a value that represents the ChangeMonitor class instance.(Inherited from ChangeMonitor.)

NameDescription
System_CAPS_pubmethodDispose()

Releases all resources that are used by the current instance of the ChangeMonitor class.(Inherited from ChangeMonitor.)

System_CAPS_protmethodDispose(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.)

System_CAPS_pubmethodEquals(Object^)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodInitializationComplete()

Called from the constructor of derived classes to indicate that initialization is finished. (Inherited from ChangeMonitor.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodNotifyOnChanged(OnChangedCallback^)

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.)

System_CAPS_protmethodOnChanged(Object^)

Called by derived classes to raise the event when a dependency changes. (Inherited from ChangeMonitor.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

The CacheEntryChangeMonitor 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 CacheEntryChangeMonitor 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.
