Base ClearCase path meaning

问题

/vobs/trms/NVaR/DSR/simulationEngine/common@@/main/2/nVARUTL.cxx@@/main/nz_mig/1

Can someone explain the meaning of the above line?

回答1:

This is an extended pathname which references:

• the version 1 of nVARUTL.cxx in branch main/nz_mig,
• itself accessible in the version 2 of the folder common in branch main

See more at "pathnames_ccase".

The @@ references the element (common or nVARUTL.cxx), followed by their versions (branches/version).

element-pname@@version-selector

Since the path starts with /vobs, it means you are accessing that version through a view set (cleartool setview) on Unix.

See as an example "About the version-extended path"

Note that each elements are selected by their own versions.

So your config spec shows only the versions of nVARUTL.cxx: /main/nz_mig/1, with branch nz_mig coming from main/14:

This has nothing to do with the version of the parent folder common.

That parent folder 'common' is selected by the version /main/2.
