+ * advanced features (e.g. deadline propagation).

+/**
+ * {@code SingleFieldBuilderV3} implements a structure that a protocol
+ * message uses to hold a single field of another protocol message. It supports
+ * the classical use case of setting an immutable {@link Message} as the value
+ * of the field and is highly optimized around this.
+ * <br>
+ * It also supports the additional use case of setting a {@link Message.Builder}
+ * as the field and deferring conversion of that {@code Builder}
+ * to an immutable {@code Message}. In this way, it's possible to maintain
+ * a tree of {@code Builder}'s that acts as a fully read/write data
+ * structure.
+ * <br>
+ * Logically, one can think of a tree of builders as converting the entire tree
+ * to messages when build is called on the root or when any method is called
+ * that desires a Message instead of a Builder. In terms of the implementation,
+ * the {@code SingleFieldBuilderV3} and {@code RepeatedFieldBuilderV3}
+ * classes cache messages that were created so that messages only need to be
+ * created when some change occurred in its builder or a builder for one of its
+ * descendants.
+ *
+ * @param <MType> the type of message for the field
+ * @param <BType> the type of builder for the field
+ * @param <IType> the common interface for the message and the builder

+/**
+ * A custom map implementation from FieldDescriptor to Object optimized to
+ * minimize the number of memory allocations for instances with a small number
+ * of mappings. The implementation stores the first {@code k} mappings in an
+ * array for a configurable value of {@code k}, allowing direct access to the
+ * corresponding {@code Entry}s without the need to create an Iterator. The
+ * remaining entries are stored in an overflow map. Iteration over the entries
+ * in the map should be done as follows:
+ *
+ * <pre>   {@code
+ * for (int i = 0; i < fieldMap.getNumArrayEntries(); i++) {
+ *   process(fieldMap.getArrayEntryAt(i));
+ * }
+ * for (Map.Entry<K, V> entry : fieldMap.getOverflowEntries()) {
+ *   process(entry);
+ * }
+ * }</pre>
+ *
+ * The resulting iteration is in order of ascending field tag number. The
+ * object returned by {@link #entrySet()} adheres to the same contract but is
+ * less efficient as it necessarily involves creating an object for iteration.
+ * <p>
+ * The tradeoff for this memory efficiency is that the worst case running time
+ * of the {@code put()} operation is {@code O(k + lg n)}, which happens when
+ * entries are added in descending order. {@code k} should be chosen such that
+ * it covers enough common cases without adversely affecting larger maps. In
+ * practice, the worst case scenario does not happen for extensions because
+ * extension fields are serialized and deserialized in order of ascending tag
+ * number, but the worst case scenario can happen for DynamicMessages.
+ * <p>
+ * The running time for all other operations is similar to that of
+ * {@code TreeMap}.
+ * <p>
+ * Instances are not thread-safe until {@link #makeImmutable()} is called,
+ * after which any modifying operation will result in an
+ * {@link UnsupportedOperationException}.
