Constructor & Destructor Documentation

ConditionalExtractor	(	Filter::View	vFilter,
		ValueExtractor::View	vExtractor,
		bool	fForwardIndex
	)			`[protected]`

Construct the ConditionalExtractor.

Parameters:

	vFilter	the filter used by this extractor to create a ConditionalIndex; must not be NULL
	vExtractor	the extractor used by this extractor to create a ConditionalIndex; Note that the created index will be associated with this extractor in the given index map; must not be NULL
	fForwardIndex	specifies whether or not this extractor will create a ConditionalIndex that supports a forward map
