org.jbpm.query.jpa.data.QueryWhere

public class QueryWhere
extends Object

THIS CLASS SHOULD NEVER BE EXPOSED IN THE PUBLIC API!!

EXTERNAL USE OF THIS CLASS IS **NOT** SUPPORTED!

This object can be seen as a (dynamic) representation of the WHERE part of a query.

It has the following responsibilities:

1. Hold a list of the added query criteria
2. Keep track of the criteria preferences:
   • Are we adding a range, a regexp or just a normal criteria?
   • Is this the start or end of a group?
