# Macro "**dataserverAttributes.{{extension}}**"

## Objective

The goal of this macro is only to master the objects `TAttribute` and {{tds}} of {{uranie}}. Three 
attributes will be created and linked to a {{tds}} object, then the *log* of this object will be printed 
to check internal data of this {{tds}}.

## Macro {{uranie}}

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc1[language] + "\n"
    + "```"
}}

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

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc2[language] + "\n"
    + "```"
}}


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

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc3[language] + "\n"
    + "```"
}}

Secondly, a {{tds}} object is created and the two attributes *x* and *y* created before are linked 
to this one.

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc4[language] + "\n"
    + "```"
}}

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

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc5[language] + "\n"
    + "```"
}}

Then, the *log* of the {{tds}} object is printed.

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes." 
    + extension 
    + "\n"
    + ":language: " + language + "\n"
    + ":lines: " + bloc6[language] + "\n"
    + "```"
}}

Generally speaking, all {{uranie}} objects have the `printLog` method which allows to print internal 
data of the object.

## Console

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/build/uranie/doc/dataserver/use_cases/" + language + "/dataserverAttributes_clean.log"
    + "\n"
    + ":language: none\n"
    + ":lines: " + bloc7[language] + "\n"
    + "```"
}}
