+     * consumer of decoded headers is represented by the callback. Then to
+     * decode the header block, the following approach might be used:

+     * <pre>{@code

+     *     ByteBuffer input = buffers.next();
+     *     decoder.decode(input, callback, !buffers.hasNext());
+     * }
+     * }</pre>
+     *
+     * <p> The decoder reads as much as possible of the header block from the
+     * given buffer, starting at the buffer's position, and increments its
+     * position to reflect the bytes read. The buffer's mark and limit will not
+     * be modified.
+     *
+     * <p> Once the method is invoked with {@code endOfHeaderBlock == true}, the
+     * current header block is deemed ended, and inconsistencies, if any, are
+     * reported immediately by throwing an {@code UncheckedIOException}.
+     *
+     * <p> Each callback method is called only after the implementation has
+     * processed the corresponding bytes. If the bytes revealed a decoding
+     * error, the callback method is not called.
+     *
+     * <p> In addition to exceptions thrown directly by the method, any
+     * exceptions thrown from the {@code callback} will bubble up.
+     *
+     * @apiNote The method asks for {@code endOfHeaderBlock} flag instead of
+     * returning it for two reasons. The first one is that the user of the
+     * decoder always knows which chunk is the last. The second one is to throw
+     * the most detailed exception possible, which might be useful for
+     * diagnosing issues.
+     *
+     * @implNote This implementation is not atomic in respect to decoding
+     * errors. In other words, if the decoding operation has thrown a decoding
+     * error, the decoder is no longer usable.
+     *
+     * @param headerBlock
+     *         the chunk of the header block, may be empty
+     * @param endOfHeaderBlock

+ * Encodes headers to their binary representation.
+ *
+ * <p>Typical lifecycle looks like this:
+ *
+ * <p> {@link #Encoder(int) new Encoder}
+ * ({@link #setMaxCapacity(int) setMaxCapacity}?
+ * {@link #encode(ByteBuffer) encode})*
+ *
+ * <p> Suppose headers are represented by {@code Map<String, List<String>>}. A
+ * supplier and a consumer of {@link ByteBuffer}s in forms of {@code
+ * Supplier<ByteBuffer>} and {@code Consumer<ByteBuffer>} respectively. Then to
+ * encode headers, the following approach might be used:
+ *
+ * <pre>{@code
+ *     for (Map.Entry<String, List<String>> h : headers.entrySet()) {
+ *         String name = h.getKey();
+ *         for (String value : h.getValue()) {
+ *             encoder.header(name, value);        // Set up header
+ *             boolean encoded;
+ *             do {
+ *                 ByteBuffer b = buffersSupplier.get();
+ *                 encoded = encoder.encode(b);    // Encode the header
+ *                 buffersConsumer.accept(b);
+ *             } while (!encoded);
+ *         }
+ *     }
+ * }</pre>
+ *
+ * <p> Though the specification <a
+ * href="https://tools.ietf.org/html/rfc7541#section-2"> does not define</a> how
+ * an encoder is to be implemented, a default implementation is provided by the
+ * method {@link #header(CharSequence, CharSequence, boolean)}.
+ *
+ * <p> To provide a custom encoding implementation, {@code Encoder} has to be
+ * extended. A subclass then can access methods for encoding using specific
+ * representations (e.g. {@link #literal(int, CharSequence, boolean) literal},
+ * {@link #indexed(int) indexed}, etc.)
+ *
+ * @apiNote
+ *
+ * <p> An Encoder provides an incremental way of encoding headers.
+ * {@link #encode(ByteBuffer)} takes a buffer a returns a boolean indicating
+ * whether, or not, the buffer was sufficiently sized to hold the
+ * remaining of the encoded representation.
+ *
+ * <p> This way, there's no need to provide a buffer of a specific size, or to
+ * resize (and copy) the buffer on demand, when the remaining encoded
+ * representation will not fit in the buffer's remaining space. Instead, an
+ * array of existing buffers can be used, prepended with a frame that encloses
+ * the resulting header block afterwards.
+ *
+ * <p> Splitting the encoding operation into header set up and header encoding,
+ * separates long lived arguments ({@code name}, {@code value}, {@code
+ * sensitivity}, etc.) from the short lived ones (e.g. {@code buffer}),
+ * simplifying each operation itself.
+ *
+ * @implNote
+ *
+ * <p> The default implementation does not use dynamic table. It reports to a
+ * coupled Decoder a size update with the value of {@code 0}, and never changes
+ * it afterwards.

+    // In order to be able to find an index of an entry with the given contents
+    // in the dynamic table an effective inverse mapping is needed. Here's a
+    // simple idea behind such a mapping.
+    //
+    // # The problem:
+    //
+    // We have a queue with an O(1) lookup by index:
+    //
+    //     get: index -> x
+    //
+    // What we also want is an O(1) reverse lookup:
+    //
+    //     indexOf: x -> index
+    //
+    // # Solution:
+    //
+    // Let's store an inverse mapping as a Map<X, Integer>. This have a problem
+    // that when a new element is added to the queue all indexes in the map
+    // becomes invalid. Namely, each i becomes shifted by 1 to the right:
+    //
+    //     i -> i + 1
+    //
+    // And the new element is assigned with an index of 1. This would seem to
+    // require a pass through the map incrementing all indexes (map values) by
+    // 1, which is O(n).
+    //
+    // The good news is we can do much better then this!
+    //
+    // Let's create a single field of type long, called 'counter'. Then each
+    // time a new element 'x' is added to the queue, a value of this field gets
+    // incremented. Then the resulting value of the 'counter_x' is then put as a
+    // value under key 'x' to the map:
+    //
+    //    map.put(x, counter_x)
+    //
+    // It gives us a map that maps an element to a value the counter had at the
+    // time the element had been added.
+    //
+    // In order to retrieve an index of any element 'x' in the queue (at any
+    // given time) we simply need to subtract the value (the snapshot of the
+    // counter at the time when the 'x' was added) from the current value of the
+    // counter. This operation basically answers the question:
+    //
+    //     How many elements ago 'x' was the tail of the queue?
+    //
+    // Which is the same as its index in the queue now. Given, of course, it's
+    // still in the queue.
+    //
+    // I'm pretty sure in a real life long overflow will never happen, so it's
+    // not too practical to add recalibrating code, but a pedantic person might
+    // want to do so:
+    //
+    //     if (counter == Long.MAX_VALUE) {
+    //         recalibrate();
+    //     }
+    //
+    // Where 'recalibrate()' goes through the table doing this:
+    //
+    //  value -= counter
+    //
+    // That's given, of course, the size of the table itself is less than
+    // Long.MAX_VALUE :-)
