public InstantiatedVersionedProcessGroup mapNonVersionedProcessGroup(ProcessGroup group,
                                                                     ControllerServiceProvider serviceProvider)

Map the given process group to a versioned process group without any use of an actual flow registry even if the group is currently versioned in a registry.

Parameters:

group - the process group to map

serviceProvider - the controller service provider to use for mapping

Returns:

a complete versioned process group without any registry related details

mapProcessGroup

public InstantiatedVersionedProcessGroup mapProcessGroup(ProcessGroup group,
                                                         ControllerServiceProvider serviceProvider,

Map the given process group to a versioned process group using the provided registry client.

Parameters:

group - the process group to map

serviceProvider - the controller service provider to use for mapping

registryClient - the registry client to use when retrieving versioning details

mapDescendantVersionedFlows - true in order to include descendant flows in the mapped result

Returns:

a complete versioned process group with applicable registry related details
