protected void meetNode(QueryModelNode node)

Description copied from class: AbstractQueryModelVisitor

Method called by all of the other meet methods that are not overridden in subclasses. This method can be overridden in subclasses to define default behaviour when visiting nodes. The default behaviour of this method is to visit the node's children.

Overrides:

meetNode in class AbstractQueryModelVisitor<RuntimeException>

Parameters:

node - The node that is being visited.
