wt.visitor.Walker

Packages that use Walker

wt.graph
wt.graph.template
wt.transfer.filter
wt.transfer.unit
wt.visitor	Defines the navigator/visitor design pattern for using a Walker (at one time it used a Navigator, instead of a Walker) and a NodeExpander, which together traverse a structure of objects, and a Visitor, which does something when we navigate to the object; this separates the algorithm for navigating from the algorithm for visiting, allowing more reuse; factories support selection of Walkers and Visitors.
