8.5. TMaster

The object inheriting from the TMaster class has a supervisor role: it defines items to be evaluated, and treats these evaluations. Usually, it is created with a TDataServer, and a TRun (TEval implicitly) that is used for evaluations. The TMaster retrieves information both:

• from TDataServer, it extracts the declaration of the input variables.

• from TEval, it extracts extra parameters that will be computed for each item.

We could distinguish two cases depending of the TDataServer data:

• if it contains a header and data, the TMaster will complete items data by adding information (columns). This happens most of the time when considering the pure launching aspect, meaning when using the TLauncher2 object, briefly defined below.

• if it contains only a header, it will be used as items definition parameters. The TMaster will fill it with its own items (lines and columns). This case happens both for pure the launching aspect, given that a design-of-experiments will be constructed at some point, but also for optimisation issues.

Disregarding the case, TMaster interface defines an abstract method, solverLoop, that runs the evaluation loop and completes or fills the TDataServer data. This method is the one to properly start the analysis.
