Methods

	Name	Description
	CalculateIteratorEffectiveness	Helper method to calculate effectiveness (or rather ineffectiveness) of a simple iteration against a key set that has to be performed due to an absence of corresponding index.
	CalculateMatchEffectiveness	Helper method to calculate effectiveness for ComparisonFilters that need no more than a single index match in order to retrieve all necessary keys to perform the applyIndex() operation. Such filters are: Contains, Equals, NotEquals.
	CalculateRangeEffectiveness	Helper method to calculate effectiveness for ComparisonFilters that need a range of values from an index in order to retrieve all necessary keys to perform the applyIndex() operation. Such filters are: Less, LessEquals, Greater, GreaterEquals.
	Equals	Compare the ComparisonFilter with another object to determine equality. (Overrides ObjectEquals(Object).)
	Evaluate	Apply the test to the object. (Inherited from ExtractorFilter.)
	EvaluateEntry	Apply the test to an ICacheEntry. (Inherited from ExtractorFilter.)
	EvaluateExtracted	Evaluate the specified extracted value. (Inherited from ExtractorFilter.)
	Extract	Gets the result of IValueExtractor invocation. (Inherited from ExtractorFilter.)
	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	Determine a hash value for the ComparisonFilter object according to the general object.GetHashCode() contract. (Overrides ObjectGetHashCode.)
	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. (Overrides ExtractorFilterReadExternal(IPofReader).)
	ToString	Return a human-readable description for this ComparisonFilter. (Overrides ObjectToString.)
	WriteExternal	Save the contents of a POF user type instance by writing its state using the specified IPofWriter object. (Overrides ExtractorFilterWriteExternal(IPofWriter).)

Fields

	Name	Description
	m_extractor	The ValueExtractor used by this filter. (Inherited from ExtractorFilter.)
	m_value	The value to compare to.
