# Methods

| Name | Description
--- | --- | ---
| ApplyFilter | Apply the specified IndexAwareFilter to the specified keySet. (Inherited from ArrayFilter.)
| ApplyIndex | Filter remaining keys using an IDictionary of available indexes. The filter is responsible for removing all keys from the passed set of keys that the applicable indexes can prove should be filtered. If the filter does not fully evaluate the remaining keys using just the index information, it must return a filter that can complete the task using an iterating implementation. If, on the other hand, the filter does fully evaluate the remaining keys using just the index information, then it should return null to indicate that no further filtering is necessary. (Inherited from AllFilter.)
| CalculateEffectiveness | Given an IDictionary of available indexes, determine if this IIndexAwareFilter can use any of the indexes to assist in its processing, and if so, determine how effective the use of that index would be. The returned value is an effectiveness estimate of how well this filter can use the specified indexes to filter the specified keys. An operation that requires no more than a single access to the index content (i.e. Equals, NotEquals) has an effectiveness of one. Evaluation of a single entry is assumed to have an effectiveness that depends on the index implementation and is usually measured as a constant number of the single operations. This number is referred to as evaluation cost. If the effectiveness of a filter evaluates to a number larger than the keys.size() then a user could avoid using the index and iterate through the keys calling evaluate rather than applyIndex. (Inherited from AllFilter.)
| CalculateFilters | Calculate the effectiveness and sort all the participating filters according to their effectiveness. (Inherited from ArrayFilter.)
| Equals | Compare the ArrayFilter with another object to determine equality. (Inherited from ArrayFilter.)
| Evaluate | Apply the test to the object. (Inherited from AllFilter.)
| EvaluateEntry | Apply the test to an ICacheEntry. (Inherited from AllFilter.)
| Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
| GetHashCode | Determine a hash value for the ArrayFilter object according to the general object.GetHashCode() contract. (Inherited from ArrayFilter.)
| GetType | Gets the Type of the current instance. (Inherited from Object.)
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.)
| ReadExternal | Restore the contents of a user type instance by reading its state using the specified IPofReader object. (Inherited from ArrayFilter.)
| ToString | Return a human-readable description for this ArrayFilter. (Inherited from ArrayFilter.)
| WriteExternal | Save the contents of a POF user type instance by writing its state using the specified IPofWriter object. (Inherited from ArrayFilter.)
