Constants

Constants are used to resolve a symbol to a number. They are defined with the Constant XML tag.

<Constant id="HIS_MET" value="12" />

Two attributes are required to define a constant:

  • id the unique identifier of the constant.

  • value the value of the constant.

A constant can then be used in a computation by prefixing it with C., e.g.:

<Computation targetArtefactTypes="APPLICATION;FOLDER;FILE;CLASS;FUNCTION" result="100*(1-(MET_KO/C.HIS_MET))" />

A constant can also be used in a scale level. Note that in this kind of usage, the constant ID does not require a prefix, as shown below:

<ScaleLevel levelId="LEVELG" bounds="]5;]" rank="HIS_MET" />
