Class StopFilter
public final class StopFilter
Removes stop words from a token stream.
static Set | makeStopSet(String[] stopWords) - Builds a Set from an array of stop words,
appropriate for passing into the StopFilter constructor.
|
static Hashtable | makeStopTable(String[] stopWords) - Use
makeStopSet(String[]) instead.
|
Token | next() - Returns the next input Token whose termText() is not a stop word.

StopFilter
public StopFilter(TokenStream in,
Hashtable stopTable)
Use StopFilter(TokenStream,Set)
instead
Constructs a filter which removes words from the input
TokenStream that are named in the Hashtable.
StopFilter
public StopFilter(TokenStream in,
Set stopWords)
Constructs a filter which removes words from the input
TokenStream that are named in the Set.
It is crucial that an efficient Set implementation is used
for maximum performance.
makeStopSet(java.lang.String[])
StopFilter
public StopFilter(TokenStream in,
String[] stopWords)
Constructs a filter which removes words from the input
TokenStream that are named in the array of words.
makeStopSet
public static final Set makeStopSet(String[] stopWords)
Builds a Set from an array of stop words,
appropriate for passing into the StopFilter constructor.
This permits this stopWords construction to be cached once when
an Analyzer is constructed.
makeStopTable
public static final Hashtable makeStopTable(String[] stopWords)
Use makeStopSet(String[])
instead.
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.
next
public final Token next()
throws IOException
Returns the next input Token whose termText() is not a stop word.
- next in interface TokenStream
