Class Description

See also:

Class InterfaceServer, Reference Messages, Class ExclList

Description:

This class facilitates taking care of node handles when merging and xref'ing scenes.

When nodes are merged, their handles will be reassigned so that their handles will not conflict with existing nodes in the scene. After the merge process has completed, all merged objects will receive a reference notification; REFMSG_NODE_HANDLE_CHANGED. The PartID (see PartID) will be a pointer to a merge manager interface that you can use to see if a specific handle was converted and convert between the old and the new handle. IMergeManager* pMergeManager = (IMergeManager*)partID; If a plug-in uses node handles in a persistent manner it has to intercept this reference message and convert the previous handles to the newly generated handles.
