Class TopLevelQueryNodeBuilder

java.lang.Object

org.sindice.siren.qparser.keyword.builders.TopLevelQueryNodeBuilder

All Implemented Interfaces:

org.apache.lucene.queryparser.flexible.core.builders.QueryBuilder, KeywordQueryBuilder

public class TopLevelQueryNodeBuilder
extends Object
implements KeywordQueryBuilder

Visits each node in a TopLevelQueryNode and wraps each NodeQuery object tagged with QueryTreeBuilder.QUERY_TREE_BUILDER_TAGID into a LuceneProxyNodeQuery.

This builder is called at the last step of the query building. If the key KeywordQueryConfigHandler.KeywordConfigurationKeys.ALLOW_TWIG is false, this builder will not be called because it is removed from the QueryNode tree (see TopLevelQueryNodeProcessor).
