lucene::analysis::StopFilter::StopFilter	(	TokenStream *	in,

Constructs a filter which removes words from the input TokenStream that are named in the CLSetList.

Member Function Documentation

static void lucene::analysis::StopFilter::fillStopTable	(	lucene::util::CLSetList< const TCHAR * > *	stopTable,
		const TCHAR **	stopWords
	)			[static]

Builds a Hashtable from an array of stop words, appropriate for passing into the StopFilter constructor.

This permits this table construction to be cached once when an Analyzer is constructed. Note: the stopWords list must be a static list because the strings are not copied

bool lucene::analysis::StopFilter::next

(

Token *

token

)

[virtual]

Returns the next input Token whose termText() is not a stop word.

Implements lucene::analysis::TokenStream.
