IComparer used to sort the index. Used iff Ordered is true. Could be null, which implicates a natural order.

Get the associated filter.

The IDictionary that contains the index contents.

IDictionary that contains the index values (forward index). The keys of the IDictionary are the keys to the indexed cache and the values are the extracted values. This map is used by IIndexAwareFilter implementations to avoid conversion and value extraction steps.

Determine whether or not this ConditionalIndex supports a forward index.

Specifies whether or not this 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.

IValueExtractor object that this ICacheIndex uses to extract an indexable Object from a [converted] value stored in the Storage. This property is never null.
