/**
    The CIMParameter class represents the DMTF standard CIM parameter
    definition.  A CIMParameter is generally defined in the context of
    a CIMMethod.
    A CIM Parameter consists of:
    <ul>
        <li>A CIMName containing the name of the parameter
        <li>A CIMType defining the parameter type
        <li>A Boolean indicating whether it is an Array parameter
        <li>A Uint32 indicating the size of the Array, if the parameter is an
            Array parameter
        <li>A CIMName containing the reference class name for this parameter,
            if the parameter is of reference type
        <li>Zero or more CIMQualifier objects
    </ul>

    <p>The CIMParameter class uses a shared representation model, such that
    multiple CIMParameter objects may refer to the same data copy.  Assignment
    and copy operators create new references to the same data, not distinct
    copies.  An update to a CIMParameter object affects all the CIMParameter
    objects that refer to the same data copy.  The data remains valid until
    all the CIMParameter objects that refer to it are destructed.  A separate
    copy of the data may be created using the clone method.
