BreadthFirstVisitor<R> class

An AST visitor that will recursively visit all of the nodes in an AST structure, similar to GeneralizingAstVisitor. This visitor uses a breadth-first ordering rather than the depth-first ordering of GeneralizingAstVisitor.

Subclasses that override a visit method must either invoke the overridden visit method or explicitly invoke the more general visit method. Failure to do so will cause the visit methods for superclasses of the node to not be invoked and will cause the children of the visited node to not be visited.

In addition, subclasses should not explicitly visit the children of a node, but should ensure that the method visitNode is used to visit the children (either directly or indirectly). Failure to do will break the order in which nodes are visited.

Note that, unlike other visitors that begin to visit a structure of nodes by asking the root node in the structure to accept the visitor, this visitor requires that clients start the visit by invoking the method visitAllNodes defined on the visitor with the root node as the argument:

visitor.visitAllNodes(rootNode);

Clients may extend this class.
