Visit All Children

Context

A design rule for implementing the visit methods of in a visitor design pattern.

The rule is probably application specific in that it needs to be tailored to a specific visitor implementation and may not be desirable to use with all visitor implementations (the restriction it imposes may be too strong).

Description

When implementing a visitor method for SomeSpecificClass in SomeSpecificClassHierarchy and SomeSpecificVisitor, ensure that you always call the visit method for each field of the visitedNode that also contains a visitable element.
