org.nuxeo.ecm.core.query.sql.model.DefaultQueryVisitor

org.nuxeo.ecm.core.storage.sql.jdbc.NXQLQueryMaker.QueryAnalyzer

All Implemented Interfaces:

IVisitor

Enclosing class:

NXQLQueryMaker

protected class NXQLQueryMaker.QueryAnalyzer
extends DefaultQueryVisitor

Collects various info about the query AST, and rewrites the toplevel AND Predicates of the WHERE clause into a single MultiExpression for easier analysis.
