Changeset 2335 for XIOS/dev

Timestamp:

06/15/22 15:20:29 (2 years ago)

Author:

Message:

Introduced a new service (named defaultServicesId which contains all gatherers and all IO servers) to manage oasis_enddef through the different levels of servers. OASIS integration is moved in a dedicated virtual class CThirdPartyDriver whose an instance is owned by CServer.
