<p>It is a simple enumeration type, but with some added member functions that can be used
to query the data type. A series of constant expressions (<code>dip::DT_XXX</code>) have been defined
that should be used when specifying a data type, there is never a need to call the
constructors to this class explicitly. It is possible to call <code>DataType</code> member functions
on these constants:</p>

<p>Note that you can add these constants together, for example <code>dip::DataType::Class_UInt8 + dip::DataType::Class_UInt16</code>.</p>
<p>It is possible to see if an image is of a type within a collection using the <code>Contains</code> method of
<code>dip::DataType::Classes</code> with a <a href="dip-DataType.html"><code>dip::DataType</code></a> as argument:</p>
<div class="m-code"><pre><span></span><span class="k">if</span><span class="p">(</span><span class="w"> </span><span class="n">dip</span><span class="o">::</span><span class="n">DataType</span><span class="o">::</span><span class="n">Class_Flex</span><span class="p">.</span><span class="n">Contains</span><span class="p">(</span><span class="w"> </span><span class="n">image</span><span class="p">.</span><span class="n">DataType</span><span class="p">()</span><span class="w"> </span><span class="p">))</span><span class="w"> </span><span class="p">{</span><span class="w"> </span><span class="p">...</span><span class="w"> </span><span class="p">}</span>
</pre></div>
<p>But more convenient is to use the <a href="dip-DataType.html#dip-DataType-IsA-Classes--C"><code>dip::DataType::IsA</code></a> method:</p>
<div class="m-code"><pre><span></span><span class="k">if</span><span class="p">(</span><span class="w"> </span><span class="n">image</span><span class="p">.</span><span class="n">DataType</span><span class="p">().</span><span class="n">IsA</span><span class="p">(</span><span class="w"> </span><span class="n">dip</span><span class="o">::</span><span class="n">DataType</span><span class="o">::</span><span class="n">Class_Flex</span><span class="w"> </span><span class="p">))</span><span class="w"> </span><span class="p">{</span><span class="w"> </span><span class="p">...</span><span class="w"> </span><span class="p">}</span>
</pre></div>
<p>This is equivalent to using one of the test functions, if defined for the specific group:</p>
<div class="m-code"><pre><span></span><span class="k">if</span><span class="p">(</span><span class="w"> </span><span class="n">image</span><span class="p">.</span><span class="n">DataType</span><span class="p">().</span><span class="n">IsFlex</span><span class="p">()</span><span class="w"> </span><span class="p">)</span><span class="w"> </span><span class="p">{</span><span class="w"> </span><span class="p">...</span><span class="w"> </span><span class="p">}</span>
