Method Detail

traceDependencies

public List traceDependencies(Collection parents,
                              boolean requiredOnly)
                       throws WTException

Given a collection of Parts or Documents, recursively trace their dependents. What links are recursively traversed to find an object's dependents varies depending upon the class of the object. EPMDocuments: EPMMemberLinks, EPMReferenceLinks and EPMVariantLinks WTParts: WTPartUsageLinks WTDocuments: WTDocumentUsageLinks Note: The notion of required does not apply to WTParts and WTDocuments. For those objects, this method always returns all of their dependents.

Supported API: false

Returns:

List of dependents

Throws:

WTException
