+/**
+ * This class allows arbitrary data structures to be inserted into, and extracted from, deep arrays
+ * and JSON-serialized strings. Say, for example, that you have this array as an input:
+ *
+ * <pre><code>['foo' => ['bar' => ['baz' => 'some_value']]]</code></pre>
+ *
+ * and you wanted to insert or extract an element. Usually, you would use:
+ *
+ * <pre><code>$array['foo']['bar']['baz'] = 'new_value';</code></pre>
+ *
+ * but sometimes you do not have access to the variable - so a string representation is needed. Using
+ * XPath-like syntax, this class allows you to do this:
+ *
+ * <pre><code>$jsonPath = new JsonPath($array);
+ * $jsonPath->set('foo.bar.baz', 'new_value');
+ * $val = $jsonPath->get('foo.bar.baz');
+ * </code></pre>
+ *
+ * @package OpenCloud\Common
