convertToSupportedObject

public Object convertToSupportedObject(int docVersion)
                                throws IOException,
                                       AutomationException

Convert the object to another object that is supported.

Remarks

This method should be used when IDocumentVersionSupportGEN::IsSupportedAtVersion returns FALSE. Calling ConvertToSupportedObject will return an IUnknown pointer to a relevant object supported at the particular ArcGIS version. Not all objects will return a supported object; in these cases a null pointer will be returned.
