All Implemented Interfaces:

Serializable, Visitor

Direct Known Subclasses:

HtmlPreformattedPartsListVisitor

public abstract class BOMPartsListVisitor
extends TextOutputVisitor
implements Serializable

This class is a Visitor that maintains a list of parts (nodes) as the structure is navigated. The usage information (links) is maintained internally. After navigation is complete, the parts list table represents the entire list of parts that make up the structure. Only parts that do not use any other parts (i.e. leaf nodes) are included. The keys in this table are the part identities and the associated value is the usage information.

Supported API: true

Extendable: true
