<div class="textblock"><h3>template&lt;class TDerived, class TNumericIdType&gt;<br />
struct zypp::base::ProvideNumericId&lt; TDerived, TNumericIdType &gt;</h3>

<p>Base class for objects providing a numeric Id. </p>
<p>The ctor creates a NumericId from some static counter.</p>
<p>The only assertion is that <code>0</code> is not used as an Id, <b>unless</b> the derived class explicitly requests this by using <a class="el" href="structzypp_1_1base_1_1ProvideNumericId.html#a550b1c880aa731cc4def5853653986ca">ProvideNumericId( const void *const )</a>.</p>
<p>Why should you want to use <code>0</code> as an Id? E.g if your class provides some (singleton) No-object. Might be desirable to make the No-object have No-Id.</p>
