Here\'s a simple example using the <code>$entity</code>-array which sets the computed field\'s value to the concatenation of fields (<code>field_a</code> and <code>field_b</code>) in an entity:
<ul>
<li><code>$value = $entity->field_a->value . $entity->field_b->value;</code></li>
</ul>
</p>
<p>
An alternative example using the <code>$fields</code>-array:
<ul>
<li><code>$value = $fields[\'field_a\'][0][\'value\'] . $fields[\'field_b\'][0][\'value\'];</code></li>
</ul>
