Method Detail
-
getField
public java.lang.String getField()
Description copied from class:SpanQuery
Returns the name of the field matched by this query.
-
createWeight
public SpanWeight createWeight(IndexSearcher searcher, ScoreMode scoreMode, float boost) throws java.io.IOException
Description copied from class:Query
Expert: Constructs an appropriate Weight implementation for this query.Only implemented by primitive queries, which re-write to themselves.
- Specified by:
createWeight
in classSpanQuery
scoreMode
- How the produced scorers will be consumed.boost
- The boost that is propagated by the parent queries.- Throws:
java.io.IOException
-
rewrite
public Query rewrite(IndexReader reader) throws java.io.IOException
Description copied from class:Query
Expert: called to re-write queries into primitive queries. For example, a PrefixQuery will be rewritten into a BooleanQuery that consists of TermQuerys.
-
visit
public void visit(QueryVisitor visitor)
Description copied from class:Query
Recurse through the query tree, visiting any child queries
-
toString
public java.lang.String toString(java.lang.String field)
Description copied from class:Query
Prints a query to a string, withfield
assumed to be the default field and omitted.
-
equals
public boolean equals(java.lang.Object other)
Description copied from class:Query
Override and implement query instance equivalence properly in a subclass. This is required so thatQueryCache
works 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 that other instance. Utility methods are provided for certain repetitive code.- Specified by:
equals
in classQuery

hashCode
public int hashCode()
Description copied from class:Query
Override and implement query hash code properly in a subclass. This is required so thatQueryCache
works properly.- Specified by:
hashCode
in classQuery
