Detailed Description

A pqPipelineSource subclass for VTK algorithms that own SMTK resources.

A single pqSMTKResource may hold different SMTK resources over its lifetime, so there is not a permanent, one-to-one correspondence between a pqSMTKResource and an smtk::resource::Resource. Indeed, a pqSMTKResource may exist with a null SMTK resource pointer. In general, a user-facing SMTK resource should never exist without a pqSMTKResource counterpart, though.

void pqSMTKResource::synchronizeResource ( )

protectedvirtualslot

Keep the pqSMTKResource and smtk::resource::Resource in sync.

This is called when the ParaView pipeline source (vtkSMTKResourceSource) has had its data modified. This can be the result of a filename change that means the old SMTK resource should be removed from the manager and a new one added. It may also be an unrelated change resulting in a modified resource, but these changes should be tracked by the operation manager, not ParaView signals/slots.
