+ * There are three variables maintained pointing into the buffer:

+ * 0 <= position <= limit <= capacity
+ *
+ * capacity: the maximum amount of data that can be stored
+ * limit: the limit of the data currently available to get or put
+ * position: the current insert or extract position
+ *
+ * In addition a mark can be set to the current position with mark(). A subsequent call to reset() will restore
+ * the position to the mark.
+ *
+ * The buffer can be marked to be little-endian (default) or big-endian. All subsequent operations will use that order.
