Methods

  Name Description
Public method Add Adds an item to the cache. If an item with the specified key already occurs in the cached, then new item is not added to the dictionary and the method return an item that is already in a cache.
Public method BulkRemove Removes items from the cache. This method is thread safe.
Public method BulkSet Adds items to the cache. If item with specified key exists in the cache, it is replaced.
Public method Clear Removes all items from the cache. This method is thread safe.
Protected method DoCleanup This method is called to cleanup the cache. Derived class must implement cleanup strategy. A lock is acquired before this method is called, which gurantees that derived class has an exclusive access to the cache dictionary. Values are tuples, where Item1 is a stop watch that is set on a last access to the item, and Item2 is an item itself.
Public method Equals Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method GetHashCode Serves as the default hash function. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Public method GetValues Gets all values.
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method Remove Removes an item from the cache. This method is thread safe.
Public method Set Adds item to the cache. If item with specified key exists in the cache, it is replaced.
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Public method TryGetValue Gets the value associated with the specified key.
