Methods

	Name	Description
	ApplyIndex	Filter remaining keys using an IDictionary of available indexes.
	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.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Evaluate	Apply the test to the object.
	EvaluateEntry	Apply the test to an ICacheEntry.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Return a human-readable description for this KeyAssociatedFilter. (Overrides Object.ToString().)

Remarks

Note: this filter is not serializable and intended to be used only internally by other composite filters to reduce the remaining key set. As of Coherence 3.2, an equivalent functionality could be achieved using the InFilter as follows:

              new InFilter(new KeyExtractor(IdentityExtractor.INSTANCE), setKeys);
