Interface NodeExpander

All Known Implementing Classes:
AbstractObjectGraphNode, BasicNodeExpander, ConfigSpecNodeExpander, EPMDocConfigSpecNodeExpander, EPMDocReqNodeExpander, NodeExpanderFactory, OccurrencedPartConfigSpecNodeExpander, ProductInstanceConfigSpecNodeExpander, ReverseConfigSpecNodeExpander, ReverseOccurrencedConfigSpecNodeExpander
public interface NodeExpander
This interface defines how nodes will be expanded (i.e. follow links from a parent node to child nodes). A class that implements this interface must provide a mechanisn for expanding a node. This includes a particular method of expansion as well as which links/roles will be used.

The NodeExpander is used to customize how a structure is navigated independent of the navigation control and the operations performed during the navigation.
