- * A generic pool class. Simpler and more efficient than goog.structs.Pool
- * because it doesn't maintain a list of objects that are in use. This class
- * has constant overhead and doesn't create any additional objects as part of
- * the pool management after construction time.
- *
- * IMPORTANT: If the objects being pooled are arrays or maps that can have
- * unlimited number of properties, they need to be cleaned before being
- * returned to the pool.
- *
- * Also note that {@see goog.object.clean} actually allocates an array to clean
- * the object passed to it, so simply using this function would defy the
- * purpose of using the pool.
- *
- * @param {number} initialCount Initial number of objects to populate the
- *     free pool at construction time.
- * @param {number} maxCount Maximum number of objects to keep in the free pool.
