methodParameters

Represents parameters.
“hierarchy node” is the ID of the hierarchy criterion for which the analysis should be performed; “transformToUtilities” means if data should be tranformed into values from range [0-1]; “boundariesProvided” means if inputsOutputs file contains information about min and max data for each factor.

The input value should be a valid XMCDA document whose main tag is <programParameters>. It must have the following form:

<programParameters>
    <parameter id="hierarchyNode">
        <values>
            <value><label>%1</label></value>
        </values>
    </parameter>
    <parameter id="transformToUtilities">
  <values>
    <value><boolean>%2</boolean></value>

</programParameters>

where:

  • %1 is a parameter named “hierarchy node”. This is a string. The default value is root.
  • %2 is a parameter named “transform to utilities”. This is a boolean. The default value is true.
  • %3 is a parameter named “boundaries provided”. This is a boolean. The default value is false.
