Procedure – Getting Representables and Representations
This section details how to use the following supported APIs and classes:
findReprentable from VisualizationHelper class – see findRepresentable
getRepresentation and getRepresentations from VisualizationHelper class – see getRepresentation
The association of Representables to Representations is one to many. The key concept when finding these relationships is to understand that when you have an EPMDocument (i.e. Representable) its Representations aren’t necessarily directly associated. In the case where an EPMDocument has an actively associated WTPart (i.e. option of creating associated parts in the workgroup manager was used when checking-in the EPMDocument), the Representations are linked to the WTPart. In all other cases the Representations are directly associated with the Representable (i.e. non-actively associated EPMDocuments, DynamicDocuments, WTParts, WTDocuments and MPMLink Representables).
