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.

- The visitor
to visit the children of this object.public DeleteClause addDeleteClause()
