<p>Both <tt class="docutils literal"><span class="pre">OpenCloud\Image\Resource\Image</span></tt> and <tt class="docutils literal"><span class="pre">OpenCloud\Image\Resource\Member</span></tt>
extend the <tt class="docutils literal"><span class="pre">AbstractSchemaResource</span></tt> class, which offers some unique functionality.</p>
<p>Because these resources are inherently dynamic - i.e. they are modelled
on dynamic JSON schema - you need to access their state in a different way
than conventional getter/setter methods, and even class properties. For this
reason, they implement SPL’s native
<a class="reference external" href="http://www.php.net/manual/en/class.arrayaccess.php">ArrayAccess</a>
interface which allows you to access their state as a conventional
array:</p>

<h2>Update image<a class="headerlink" href="#update-image" title="Permalink to this headline">¶</a></h2>
<p>You can only update your own custom images - you cannot update or delete
base images. The way in which you may update your image is dictated by
its <a class="reference external" href="schemas">schema</a>.</p>
<p>Although you should be able to add new and replace existing properties,
always prepare yourself for a situation where it might be forbidden:</p>
<div class="highlight-php"><div class="highlight"><pre><span class="k">use</span> <span class="nx">OpenCloud\Common\Exceptions\ForbiddenOperationException</span><span class="p">;</span>

<p>There are three operations that can take place for each Image property:</p>
<ul class="simple">
<li>If a <tt class="docutils literal"><span class="pre">false</span></tt> or <tt class="docutils literal"><span class="pre">null</span></tt> value is provided, a <tt class="docutils literal"><span class="pre">REMOVE</span></tt> operation
will occur, removing the property from the JSON document</li>
<li>If a non-false value is provided and the property does not exist, an
<tt class="docutils literal"><span class="pre">ADD</span></tt> operation will add it to the document</li>
<li>If a non-false value is provided and the property does exist, a
<tt class="docutils literal"><span class="pre">REPLACE</span></tt> operation will modify the property in the document</li>
