the class Freezer method clone.

/**
 * Returns an unmodifiable copy of the specified object.
 * This method performs the following heuristic tests:
 *
 * <ul>
 *   <li>If the specified object is an instance of {@code ModifiableMetadata},
 *       then {@link ModifiableMetadata#unmodifiable()} is invoked on that object.</li>
 *   <li>Otherwise, if the object is a {@linkplain Collection collection}, then the
 *       content is copied into a new collection of similar type, with values replaced
 *       by their unmodifiable variant.</li>
 *   <li>Otherwise, if the object implements the {@link Cloneable} interface,
 *       then a clone is returned.</li>
 *   <li>Otherwise, the object is assumed immutable and returned unchanged.</li>
 * </ul>
 *
 * @param  object  the object to convert in an immutable one.
 * @return a presumed immutable view of the specified object.
