+ * An array of cacheable objects.
+ *
+ * This class allows a developer to create an array of cacheable objects and store that.
+ * The cache API doesn't check items within an array to see whether they are cacheable. Such a check would be very costly to both
+ * arrays using cacheable object and those that don't.
+ * Instead the developer must explicitly use a cacheable_object_array instance.
+ *
+ * The following is one example of how this class can be used.
+ * <code>
+ * $data = array();
+ * $data[] = new cacheable_object('one');
+ * $data[] = new cacheable_object('two');
+ * $data[] = new cacheable_object('three');
+ * $cache->set(new cacheable_object_array($data));
+ * </code>
+ * Another example would be
+ * <code>
+ * $data = new cacheable_object_array();
+ * $data[] = new cacheable_object('one');
+ * $data[] = new cacheable_object('two');
+ * $data[] = new cacheable_object('three');
+ * $cache->set($data);
+ * </code>
