Method Detail

createWeight
public abstract Weight createWeight(IndexSearcher searcher, ScoreMode scoreMode, float boost) throws IOException
Description copied from class:QueryExpert: Constructs an appropriate Weight implementation for this query.Only implemented by primitive queries, which re-write to themselves.
- Overrides:
createWeightin classQueryscoreMode- How the produced scorers will be consumed.boost- The boost that is propagated by the parent queries.- Throws:
IOException
-
toString
public String toString(String field)
Description copied from class:QueryPrints a query to a string, withfieldassumed to be the default field and omitted.
-
equals
public boolean equals(Object o)
Description copied from class:QueryOverride and implement query instance equivalence properly in a subclass. This is required so thatQueryCacheworks properly.Typically a query will be equal to another only if it's an instance of the same class and its document-filtering properties are identical to those of the other instance. Utility methods are provided for certain repetitive code.

visit
public void visit(QueryVisitor visitor)
Description copied from class:QueryRecurse through the query tree, visiting any child queries.
-
hashCode
public int hashCode()
Description copied from class:QueryOverride and implement query hash code properly in a subclass. This is required so thatQueryCacheworks properly.- Specified by:
