public void accept(ExpressionVisitor visitor)
Expression
by the given visitor
.visitor
- The visitor
to visit this objectpublic 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()
or Expression.getChildren()
is called.
This does not traverse the Expression
sub-hierarchy, use an subclass of
AbstractTraverseChildrenVisitor
in order to traverse the entire sub-hierarchy.
