public interface IObservableCache : ICache, 
	IDictionary, ICollection, IEnumerable

The IObservableCache type exposes the following members.

Properties

	Name	Description
	Count	Gets the number of elements contained in the ICollection. (Inherited from ICollection.)
	Entries	Gets a collection of ICacheEntry instances within the cache. (Inherited from ICache.)
	IsFixedSize	Gets a value indicating whether the IDictionary object has a fixed size. (Inherited from IDictionary.)
	IsReadOnly	Gets a value indicating whether the IDictionary object is read-only. (Inherited from IDictionary.)
	IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.)
	Item	Gets or sets the element with the specified key. (Inherited from IDictionary.)
	Keys	Gets an ICollection object containing the keys of the IDictionary object. (Inherited from IDictionary.)
	SyncRoot	Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.)
	Values	Gets an ICollection object containing the values in the IDictionary object. (Inherited from IDictionary.)

Methods

	Name	Description
	Add	Adds an element with the provided key and value to the IDictionary object. (Inherited from IDictionary.)
	AddCacheListener(ICacheListener)	Add a standard cache listener that will receive all events (inserts, updates, deletes) that occur against the cache, with the key, old-value and new-value included.
	AddCacheListener(ICacheListener, Object, Boolean)	Add a cache listener for a specific key.
	AddCacheListener(ICacheListener, IFilter, Boolean)	Add a cache listener that receives events based on a filter evaluation.
	Clear	Removes all elements from the IDictionary object. (Inherited from IDictionary.)
	Contains	Determines whether the IDictionary object contains an element with the specified key. (Inherited from IDictionary.)
	CopyTo	Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.)
	GetAll	Get the values for all the specified keys, if they are in the cache. (Inherited from ICache.)
	GetEnumerator	Returns an ICacheEnumerator object for the ICache instance. (Inherited from ICache.)
	Insert(Object, Object)	Associates the specified value with the specified key in this cache. (Inherited from ICache.)
	Insert(Object, Object, Int64)	Associates the specified value with the specified key in this cache. (Inherited from ICache.)
	InsertAll	Copies all of the mappings from the specified dictionary to this cache (optional operation). (Inherited from ICache.)
	Remove	Removes the element with the specified key from the IDictionary object. (Inherited from IDictionary.)
	RemoveCacheListener(ICacheListener)	Remove a standard cache listener that previously signed up for all events.
	RemoveCacheListener(ICacheListener, Object)	Remove a cache listener that previously signed up for events about a specific key.
	RemoveCacheListener(ICacheListener, IFilter)	Remove a cache listener that previously signed up for events based on a filter evaluation.

Remarks

This is primarily intended for caches that have automatic pruning and purging strategies or caches that are asynchronously modified by different threads.
