Returns the actual identifier found in the string representation of the JPQL query, which has
the actual case that was used.

public void acceptChildren(ExpressionVisitor visitor)
Expression
. This method can be used to optimize traversing
the children since a new list is not created every time Expression.children()
is called.
This does not traverse the Expression
sub-hierarchy, use a subclass of
AbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.
