NO_DEF

NoDefault

is_nodefault

Special new data type for no-default.
Not often needed by the end-user, mainly internal.<ul>
<li><code>NoDefault</code>: R6 factory.</li>
<li><code>NO_DEF</code>: R6 Singleton object for type, used in <a rd-options="" href="/link/Param?package=paradox&version=0.8.0" data-mini-rdoc="paradox::Param">Param</a>.</li>
<li><code>is_nodefault()</code>: Is an object of type 'no default'?</li>
</ul>

Define parameter spaces, constraints and
dependencies for arbitrary algorithms, to program on such spaces. Also
includes statistical designs and random samplers. Objects are
implemented as 'R6' classes.
