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.

Supported API: true

Extendable: true

Method Summary
