13.3.1. Macro “dataserverAttributes.py”

13.3.1.1. 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.

Example of attribute management

from URANIE import DataServer

# Define the attribute "x"
px = DataServer.TAttribute("x", -2.0, 4.0)
px.setTitle("#Delta P^{#sigma}")
px.setUnity("#frac{mm^{2}}{s}")

# Define the attribute "y"
py = DataServer.TAttribute("y", 0.0, 1.0)

# Define the DataServer of the study
tds = DataServer.TDataServer("tds", "my first TDS")

# Add the attributes in the DataServer.TDataServer
tds.addAttribute(px)
tds.addAttribute(py)
tds.addAttribute(DataServer.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 \(\frac{mm^{2}}{s}\)

px = DataServer.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.

py = DataServer.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.

tds = DataServer.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(DataServer.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.
