Method Detail

meetNode

protected void meetNode(QueryModelNode node)

Description copied from class: QueryModelVisitorBase

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 QueryModelVisitorBase<RuntimeException>

Parameters:

node - The node that is being visited.
