All Implemented Interfaces:

Serializable, Visitor

Direct Known Subclasses:

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

Method Detail

getPartsList

public Hashtable getPartsList()

Gets the object for the association that plays role: partsList.

Supported API: true

Returns:

Hashtable

visit

public final boolean visit(Persistable fromNode,
                           Link link,
                           Persistable toNode,
                           int level,
                           boolean previouslyVisited)
                    throws WTException

Visit a node. Information is stored in an internal hash table for this link and node. A boolean true value is always returned so that every node is visited.

Supported API: true

Specified by:

visit in interface Visitor

Overrides:

visit in class VisitorAdapter

Parameters:

fromNode -

link -

toNode -

level -

previouslyVisited -

Returns:

boolean

Throws:

WTException

report

public abstract void report()

This operation outputs a text report of the internal parts list. This operation should only be called after navigation is complete.

Supported API: true

getParentNodeAttributes

private Object getParentNodeAttributes(Persistable node)
                                throws WTException

Throws:

WTException

getLinkAttributes

private Object getLinkAttributes(Link link)
                          throws WTException

This method gets the attributes for this link.

Throws:

WTException

processAttributes

private Object processAttributes(Object previousAttributes,
                                 Object attributes,
                                 int operation)
                          throws WTException

This method processes the previous and current attributes as specified by the operation parameter.

Throws:

WTException
