Detailed Description

Implementation of a visitor that creates a map of pairs [name,QueryTreeField] for all defined identifiers of the query.

Author:

Christophe Ney [cney@batisseurs.com] Initial developper

Helene Joanin:

In the visit of the SELECT clause, do not forget to add the id in the ids structure if its not present. Indeed, the definition of this id is done in the FROM clause which is visited later. This is needed for ejbSelect query which allows path_expression in the SELECT clause.
Use of the NavigatorNodeFactory.getIn() for IN in the FROM part instead of NavigatorNodeFactory.getNavigatorNode()
Some modifications needed to take into account CollectionValuedPathExpression for the member of and is empty operators.
For the MemberOf implementation, do not more build an unique QueryTree, but a Map of pairs [name,QueryTreeField]
Add the ORDER BY clause.
Take into account the new interface of NavigatorNodeFactory.
IS EMPTY / IS NOT EMPTY
Take into account the EJBQL version 2.1 syntax.
