DistanceQuery

public DistanceQuery(List<SrndQuery> queries,
                     boolean infix,
                     int opDistance,
                     String opName,
                     boolean ordered)

Method Detail

getOpDistance

public int getOpDistance()

subQueriesOrdered

public boolean subQueriesOrdered()

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.
