+     * This class defines six categories of operations upon byte buffers:
+     *
+     *  1. Absolute and relative get and put methods that read and write single bytes;
+     *  2. Relative bulk get methods that transfer contiguous sequences of bytes from
+     *     this buffer into an array;
+     *  3. Relative bulk put methods that transfer contiguous sequences of bytes from
+     *     a byte array or some other byte buffer into this buffer;
+     *  4. Absolute and relative get and put methods that read and write values of other
+     *     primitive types, translating them to and from sequences of bytes in a
+     *     particular byte order;
+     *  5. Methods for creating view buffers, which allow a byte buffer to be viewed as
+     *     a buffer containing values of some other primitive type; and
+     *  6. Methods for compacting, duplicating, and slicing a byte buffer.
+     *
+     * Byte buffers can be created either by allocation, which allocates space for the
+     * buffer's content, or by wrapping an existing byte array into a buffer.
+     *
+     * Access to binary data:
+     *
+     * This class defines methods for reading and writing values of all other primitive
+     * types, except boolean. Primitive values are translated to (or from) sequences of
+     * bytes according to the buffer's current byte order.
+     *
+     * For access to heterogeneous binary data, that is, sequences of values of
+     * different types, this class defines a family of absolute and relative get and
+     * put methods for each type. For 32-bit floating-point values, for example, this
+     * class defines:
+     *
+     *   float getFloat()
+     *   float getFloat(int index)
+     *   void  putFloat(float f)
+     *   void  putFloat(int index, float f)
+     *
+     * Corresponding methods are defined for the types char, short, int, long, and
+     * double. The index parameters of the absolute get and put methods are in terms
+     * of bytes rather than of the type being read or written.
+     *
+     * For access to homogeneous binary data, that is, sequences of values of the same
+     * type, this class defines methods that can create views of a given byte buffer.
+     * A view buffer is simply another buffer whose content is backed by the byte buffer.
+     * Changes to the byte buffer's content will be visible in the view buffer, and vice
+     * versa; the two buffers' position, limit, and mark values are independent. The
+     * asFloatBuffer method, for example, creates an instance of the FloatBuffer class
+     * that is backed by the byte buffer upon which the method is invoked. Corresponding
+     * view-creation methods are defined for the types char, short, int, long, and double.
+     *
+     * View buffers have two important advantages over the families of type-specific
+     * get and put methods described above:
+     *
+     *   A view buffer is indexed not in terms of bytes but rather in terms of the
+     *   type-specific size of its values;
+     *
+     *   A view buffer provides relative bulk get and put methods that can transfer
+     *   contiguous sequences of values between a buffer and an array or some other
+     *   buffer of the same type; and
+     *
