public abstract class AbstractKeySetBasedCache : AbstractKeyBasedCache
The AbstractKeySetBasedCache type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | AbstractKeySetBasedCache | Initializes a new instance of the AbstractKeySetBasedCache class |
Properties| Name | Description | |
|---|---|---|
 | Count |
Returns the number of key-value mappings in this cache.
(Overrides AbstractKeyBasedCacheCount.) |
| Entries |
Returns a collection of the mappings contained in this cache.
(Inherited from AbstractKeyBasedCache.) |
| IsFixedSize |
Gets a value indicating whether the IDictionary object has
a fixed size.
(Inherited from AbstractKeyBasedCache.) |
| IsReadOnly |
Gets a value indicating whether the IDictionary object is
read-only.
(Inherited from AbstractKeyBasedCache.) |
| IsSynchronized |
Gets a value indicating whether access to the ICollection
is synchronized (thread safe).
(Inherited from AbstractKeyBasedCache.) |
| Item |
Returns the value to which this cache maps the specified key.
(Inherited from AbstractKeyBasedCache.) |
| Keys |
Returns a collection view of the keys contained in this cache.
(Inherited from AbstractKeyBasedCache.) |
| SyncRoot |
Gets an object that can be used to synchronize access to the
ICollection.
(Inherited from AbstractKeyBasedCache.) |
| Values |
Returns a collection of the values contained in this cache.
(Inherited from AbstractKeyBasedCache.) |
Methods| Name | Description | |
|---|---|---|
 | Add |
Adds an element with the provided key and value to the
IDictionary object.
(Inherited from AbstractKeyBasedCache.) |
| Clear |
Clear all key/value mappings.
(Inherited from AbstractKeyBasedCache.) |
| Contains |
Returns true if this cache contains a mapping for the
specified key.
(Overrides AbstractKeyBasedCacheContains(Object).) |
| CopyTo |
Copies the elements of the ICollection to an Array,
starting at a particular index.
(Inherited from AbstractKeyBasedCache.) |
| Equals |
Compares the specified object with this cache for equality.
(Inherited from AbstractKeyBasedCache.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| Get |
Returns the value for the specified key.
(Inherited from AbstractKeyBasedCache.) |
| GetAll |
Get all the specified keys, if they are in the cache.
(Inherited from AbstractKeyBasedCache.) |
| GetEnumerator |
Returns an ICacheEnumerator object for the
ICache instance.
(Inherited from AbstractKeyBasedCache.) |
| GetHashCode |
Returns the hash code value for this cache.
(Inherited from AbstractKeyBasedCache.) |
| GetInternalKeysCollection |
Obtain a collection of keys that are represented by this cache.
|
| GetKeysEnumerator |
Create an IEnumerator over the keys in this cache.
(Overrides AbstractKeyBasedCacheGetKeysEnumerator.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| Insert(Object, Object) |
Associates the specified value with the specified key in this
cache.
(Inherited from AbstractKeyBasedCache.) |
| Insert(Object, Object, Int64) |
Associates the specified value with the specified key in this
cache.
(Inherited from AbstractKeyBasedCache.) |
| InsertAll |
Copies all of the mappings from the specified IDictionary
to this cache.
(Inherited from AbstractKeyBasedCache.) |
| InstantiateEntriesCollection |
Factory pattern: Create a collection that represents the entries
in the cache.
(Inherited from AbstractKeyBasedCache.) |
| InstantiateKeyEnumerator |
Factory pattern: Create an IEnumerator over the keys in
the cache.
|
| InstantiateKeysCollection |
Factory pattern: Create a collection that represents the keys in
the cache.
(Inherited from AbstractKeyBasedCache.) |
| InstantiateValuesCollection |
Factory pattern: Instantiate the values collection.
(Inherited from AbstractKeyBasedCache.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| Remove |
Removes the mapping for this key from this cache if present.
(Inherited from AbstractKeyBasedCache.) |
| RemoveBlind |
Removes the mapping for this key from this cache if present.
(Inherited from AbstractKeyBasedCache.) |
| ToString |
Returns a string representation of this cache.
(Inherited from AbstractKeyBasedCache.) |
RemarksAs a result, it is possible to optimize the implementation of a number of methods that benefit from a knowledge of the entire set of keys.
Read-only implementations must implement GetInternalKeysCollection and Get(Object). Read/write implementations must additionally implement Insert(Object, Object, Int64) and Remove(Object). If the implementation has any cost of returning an "old value", then the InsertAll(IDictionary) and RemoveBlind(Object) methods should also be implemented. The only other obvious method for optimization is Clear, if the implementation is able to do it in bulk.
