Based on your schema below, torque will generate methods like:
Project.getProjectUsers(Criteria)
and
User.getProjectUsers(Criteria)
you can use these methods to build better named methods, similar to
this:
Project.java
public List getUsers(Criteria crit)
{
List pus = getProjectUsers(crit);
List users = new ArrayList(pus.size());
Iterator i = pus.iterator();
while (i.hasNext())
{
users.add( ((ProjectUser)i.next()).getUser() );
}
return users;
}
