compareTo

@Deprecated
public int compareTo(SimpleTerm ost)

Deprecated.

(March 2011) Not normally used, to be removed from Lucene 4.0. This class implementing Comparable is to be removed at the same time.

Specified by:

visitMatchingTerms

public abstract void visitMatchingTerms(IndexReader reader,
                                        String fieldName,
                                        SimpleTerm.MatchingTermVisitor mtv)
                                 throws IOException

Throws:

IOException

distanceSubQueryNotAllowed

public String distanceSubQueryNotAllowed()

Description copied from interface: DistanceSubQuery

When distanceSubQueryNotAllowed() returns non null, the reason why the subquery is not allowed as a distance subquery is returned.
When distanceSubQueryNotAllowed() returns null addSpanNearQueries() can be used in the creation of the span near clause for the subquery.

Specified by:

distanceSubQueryNotAllowed in interface DistanceSubQuery

addSpanQueries

public void addSpanQueries(SpanNearClauseFactory sncf)
                    throws IOException

Specified by:

addSpanQueries in interface DistanceSubQuery

Throws:

IOException
