13.2.1. Macro “dataserverAttributes.C”

13.2.1.1. Objective

The goal of this macro is only to master the objects TAttribute and TDataServer of Uranie. Three attributes will be created and linked to a TDataServer object, then the log of this object will be printed to check internal data of this TDataServer.

13.2.1.2. Macro Uranie

    // Define the DataServer of the study
    TDataServer *tds = new TDataServer("tds", "my first TDS");

    // Define the attribute "x"
    TAttribute *px = new TAttribute("x", -2.0, 4.0);
    px->setTitle("#Delta P^{#sigma}");
    px->setUnity("#frac{mm^{2}}{s}");

    // Define the attribute "y"
    TAttribute *py = new TAttribute("y", 0.0, 1.0);

    // Add the attributes in the TDataServer
    tds->addAttribute(px);
    tds->addAttribute(py);

    tds->addAttribute(new TAttribute("z", 0.25, 0.50));

    tds->printLog();

The first attribute “x” is defined on [-2.0, 4.0]; its title is \(\Delta P^{\sigma}\) and unity \(\frac{mm^{2}}{s}\)

    TAttribute *px = new TAttribute("x", -2.0, 4.0);
    px->setTitle("#Delta P^{#sigma}");
    px->setUnity("#frac{mm^{2}}{s}");

The second attribute “y” is defined on [0.0,1.0]; it will be set with its name as title but without unity.

    TAttribute *py = new TAttribute("y", 0.0, 1.0);

Secondly, a TDataServer object is created and the two attributes x and y created before are linked to this one.

    TDataServer *tds = new TDataServer("tds", "my first TDS");
    tds->addAttribute(px);
    tds->addAttribute(py);

Finally, the last attribute z (defined on [0.25,0.50]) is directly added to the TDataServer (its title will be its name and it will be set without unity) by creating it. An attribute could, indeed, be added to a TDataServer meanwhile creating it, but then no other information than those available in the constructor would be set.

    tds->addAttribute(new TAttribute("z", 0.25, 0.50));

Then, the log of the TDataServer object is printed.

    tds->printLog();

Generally speaking, all Uranie objects have the printLog method which allows to print internal data of the object.
