Update this index in response to a remove operation on a cache.

Using the index information if possible, get the value associated with the specified key. This is expected to be more efficient than using the IValueExtractor against an object containing the value, because the index should already have the necessary information at hand.

Update this index in response to a insert operation on a cache.

Update this index in response to a update operation on a cache.

The IComparer used to sort the index.

Get the IDictionary that contains the index contents.

Determine if the ICacheIndex orders the contents of the indexed information.

Determine if indexed information for any entry in the indexed ICache has been excluded from this index. This information is used by IIndexAwareFilter implementations to determine the most optimal way to apply the index.

Obtain the IValueExtractor object that the ICacheIndex uses to extract an indexable Object from a value stored in the indexed ICache. This property is never null.
