Class LuceneQueryBuilder

java.lang.Object

org.apache.jackrabbit.core.query.lucene.LuceneQueryBuilder

All Implemented Interfaces:

org.apache.jackrabbit.spi.commons.query.QueryNodeVisitor

public class LuceneQueryBuilder
extends Object
implements org.apache.jackrabbit.spi.commons.query.QueryNodeVisitor

Implements a query builder that takes an abstract query tree and creates a lucene Query tree that can be executed on an index. todo introduce a node type hierarchy for efficient translation of NodeTypeQueryNode

                                                  throws RepositoryException

Creates a lucene Query tree from an abstract query tree.

Parameters:

root - the root node of the abstract query tree.

session - of the user executing the query.

sharedItemMgr - the shared item state manager of the workspace.

nsMappings - namespace resolver for internal prefixes.

analyzer - for parsing the query statement of the contains function.

propReg - the property type registry to lookup type information.

synonymProvider - the synonym provider or null if node is configured.

indexFormatVersion - the index format version to be used

Returns:

the lucene query tree.

Throws:

RepositoryException - if an error occurs during the translation.
