                       int[] min,

Method Detail

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 that QueryCache 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 class BinaryRangeFieldRangeQuery

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 that QueryCache works properly.

Overrides:

hashCode in class BinaryRangeFieldRangeQuery

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 class BinaryRangeFieldRangeQuery

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, with field assumed to be the default field and omitted.

Specified by:

toString in class Query

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.

Overrides:

rewrite in class BinaryRangeFieldRangeQuery

Throws:

java.io.IOException

encodeRanges

private static byte[] encodeRanges(int[] min,
                                   int[] max)
