Class FixedBooleanQuery

java.lang.Object

org.apache.lucene.search.Query

org.graylog.plugins.views.search.validation.FixedBooleanQuery

All Implemented Interfaces:

Iterable<org.apache.lucene.search.BooleanClause>

public class FixedBooleanQuery
extends org.apache.lucene.search.Query
implements Iterable<org.apache.lucene.search.BooleanClause>

The default BooleanQuery from lucene uses Multiset implementations in the visit method. These lose the reference to the actual query instance and aggregate queries if they are the same. This breaks our terms detection in validation. So we have to provide this alternative class that iterates bool clauses with correct references

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object obj)

Spliterator<org.apache.lucene.search.BooleanClause>	spliterator()
String	toString(String field)
void	visit(org.apache.lucene.search.QueryVisitor visitor) This is the only purpose of this class - provide a simpler visit method that preserves the query reference to the underlying object.

iterator

public Iterator<org.apache.lucene.search.BooleanClause> iterator()

Specified by:

iterator in interface Iterable<org.apache.lucene.search.BooleanClause>

forEach

public void forEach(Consumer<? super org.apache.lucene.search.BooleanClause> consumer)

Specified by:

forEach in interface Iterable<org.apache.lucene.search.BooleanClause>

spliterator

public Spliterator<org.apache.lucene.search.BooleanClause> spliterator()

Specified by:

spliterator in interface Iterable<org.apache.lucene.search.BooleanClause>

visit

public void visit(org.apache.lucene.search.QueryVisitor visitor)

This is the only purpose of this class - provide a simpler visit method that preserves the query reference to the underlying object. That reference is then used to obtain related query terms during validation.
