equals
public boolean equals(java.lang.Object obj)
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.
- Overrides:
equals
in classBinaryRangeFieldRangeQuery
- See Also:
Query.sameClassAs(Object)
,Query.classHash()
-
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.- Overrides:
hashCode
in classBinaryRangeFieldRangeQuery
- See Also:
Query.equals(Object)
-
visit
public void visit(QueryVisitor visitor)
Description copied from class:Query
Recurse through the query tree, visiting any child queries- Overrides:
visit
in classBinaryRangeFieldRangeQuery
- Parameters:
visitor
- a QueryVisitor to be called by each query in the tree
-
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.
-
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.Callers are expected to call
rewrite
multiple times if necessary, until the rewritten query is the same as the original query.- Overrides:
rewrite
in classBinaryRangeFieldRangeQuery
- Throws:
java.io.IOException
- See Also:
IndexSearcher.rewrite(Query)
-
encodeRanges
private static byte[] encodeRanges(double[] min, double[] max)
