All Implemented Interfaces:

QueryModelVisitor<RuntimeException>

public class QueryModelTreePrinter
extends QueryModelVisitorBase<RuntimeException>

QueryModelVisitor implementation that "prints" a tree representation of a query model. The tree representations is printed to an internal character buffer and can be retrieved using getTreeString(). As an alternative, the static utility method printTree(QueryModelNode) can be used.

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:
