methodParameters

Represents method parameters (tolerance).

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

<programParameters>

    </parameter>
</programParameters>

where:

  • %1 is a parameter named “tolerance”. This is a float, and the value should conform to the following constraint: The value should be a non-negative number.. More formally, the constraint is:

    %1 >= 0

    The default value is 0.00.
