 <div class="block">Specification about how to estimate a domain of validity for transforms.
  Contrarily to <a href="../../CRS.html#getDomainOfValidity(org.opengis.referencing.crs.CoordinateReferenceSystem)">CRS domain of validity</a>,
  this class estimates a domain based on mathematical behavior only, not on "real world" considerations.
  For example, the Mercator projection tends to infinity when approaching poles, so it is recommended to
  not use it above some latitude threshold, typically 80° or 84°. The exact limit is arbitrary.
  This is different than the domain of validity of CRS, which is often limited to a particular country.
  In general, the CRS domain of validity is much smaller than the domain computed by this class.

  <p>Current implementation does not yet provide ways to describe how a domain is decided.
  A future version may, for example, allows to specify a maximal deformation tolerated for map projections.
  In current implementation, the estimation can be customized by overriding the
  <a href="#estimate(org.opengis.referencing.operation.MathTransform)"><code>estimate(MathTransform)</code></a> or <a href="#intersect(org.opengis.geometry.Envelope)"><code>intersect(Envelope)</code></a> methods.</p>

  <p>Each <code>DomainDefinition</code> instance should be used only once for an <a href="AbstractMathTransform.html" title="class in org.apache.sis.referencing.operation.transform"><code>AbstractMathTransform</code></a>
  instance, unless that transform is a chain of concatenated transforms (this case is handled automatically
  by Apache SIS). Usage example:</p>


 <div class="snippet-container"><button class="copy snippet-copy" aria-label="Copy snippet" onclick="copySnippet(this)"><span data-copied="Copied!">Copy</span><img src="../../../../../../../copy.svg" alt="Copy snippet"></button>
 <pre class="snippet"><code class="language-java">AbstractMathTransform transform = …;
 transform.getDomain(new DomainDefinition()).ifPresent((domain) -&gt; {
     // Do something here with the transform domain.
 });
 </code></pre>
 </div>


  The <a href="MathTransforms.html#getDomain(org.opengis.referencing.operation.MathTransform)"><code>MathTransforms.getDomain(MathTransform)</code></a> convenience method can be used
  when the default implementation is sufficient.</div>
