EjbqlVariableVisitor
public class EjbqlVariableVisitor extends EjbqlAbstractVisitor (Code)
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
author:
   Helene Joanin:
author:
  

    author:
      
  • In the visit of the SELECT clause, do not forget to add the id
    author:
       in the ids structure if its not present. Indeed, the definition of
    author:
       this id is done in the FROM clause which is visited later. This is
    author:
       needed for ejbSelect query which allows path_expression in the SELECT
    author:
       clause.

  • author:
      
  • Use of the NavigatorNodeFactory.getIn() for IN in the FROM part
    author:
       instead of NavigatorNodeFactory.getNavigatorNode()

  • author:
      
  • Some modifications needed to take into account CollectionValuedPathExpression
    author:
       for the member of and is empty operators.

  • author:
      
  • For the MemberOf implementation, do not more build an unique
    author:
       QueryTree, but a Map of pairs [name,QueryTreeField]

  • author:
      
  • Add the ORDER BY clause.

  • author:
      
  • Take into account the new interface of NavigatorNodeFactory.

  • author:
      
  • IS EMPTY / IS NOT EMPTY

  • author:
      
  • Take into account the EJBQL version 2.1 syntax.
