+/**
+ * A table of known extensions, searchable by name or field number. When
+ * parsing a protocol message that might have extensions, you must provide
+ * an {@code ExtensionRegistry} in which you have registered any extensions
+ * that you want to be able to parse. Otherwise, those extensions will just
+ * be treated like unknown fields.
+ *
+ * <p>For example, if you had the {@code .proto} file:
+ *
+ * <pre>
+ * option java_class = "MyProto";
+ *
+ * message Foo {
+ * extensions 1000 to max;
+ * }
+ *
+ * extend Foo {
+ * optional int32 bar;
+ * }
+ * </pre>
+ *
+ * Then you might write code like:
+ *
+ * <pre>
+ * ExtensionRegistry registry = ExtensionRegistry.newInstance();
+ * registry.add(MyProto.bar);
+ * MyProto.Foo message = MyProto.Foo.parseFrom(input, registry);
+ * </pre>
+ *
+ * <p>Background:
+ *
+ * <p>You might wonder why this is necessary. Two alternatives might come to
+ * mind. First, you might imagine a system where generated extensions are
+ * automatically registered when their containing classes are loaded. This
+ * is a popular technique, but is bad design; among other things, it creates a
+ * situation where behavior can change depending on what classes happen to be
+ * loaded. It also introduces a security vulnerability, because an
+ * unprivileged class could cause its code to be called unexpectedly from a
+ * privileged class by registering itself as an extension of the right type.
+ *
+ * <p>Another option you might consider is lazy parsing: do not parse an
+ * extension until it is first requested, at which point the caller must
+ * provide a type to use. This introduces a different set of problems. First,
+ * it would require a mutex lock any time an extension was accessed, which
+ * would be slow. Second, corrupt data would not be detected until first
+ * access, at which point it would be much harder to deal with it. Third, it
+ * could violate the expectation that message objects are immutable, since the
+ * type provided could be any arbitrary message class. An unprivileged user
+ * could take advantage of this to inject a mutable object into a message
+ * belonging to privileged code and create mischief.

+/**
+ * Equivalent to {@link ExtensionRegistry} but supports only "lite" types.
+ * <p>
+ * If all of your types are lite types, then you only need to use
+ * {@code ExtensionRegistryLite}. Similarly, if all your types are regular
+ * types, then you only need {@link ExtensionRegistry}. Typically it does not
+ * make sense to mix the two, since if you have any regular types in your
+ * program, you then require the full runtime and lose all the benefits of
+ * the lite runtime, so you might as well make all your types be regular types.
+ * However, in some cases (e.g. when depending on multiple third-party libraries
+ * where one uses lite types and one uses regular), you may find yourself
+ * wanting to mix the two. In this case things get more complicated.
+ * <p>
+ * There are three factors to consider: Whether the type being extended is
+ * lite, whether the embedded type (in the case of a message-typed extension)
+ * is lite, and whether the extension itself is lite. Since all three are
+ * declared in different files, they could all be different. Here are all
+ * the combinations and which type of registry to use:
+ * <pre>
+ * Extended type Inner type Extension Use registry
+ * =======================================================================
+ * lite lite lite ExtensionRegistryLite
+ * lite regular lite ExtensionRegistry
+ * regular regular regular ExtensionRegistry
+ * all other combinations not supported
+ * </pre>
+ * <p>
+ * Note that just as regular types are not allowed to contain lite-type fields,
+ * they are also not allowed to contain lite-type extensions. This is because
+ * regular types must be fully accessible via reflection, which in turn means
+ * that all the inner messages must also support reflection. On the other hand,
+ * since regular types implement the entire lite interface, there is no problem
+ * with embedding regular types inside lite types.

+ * generates a string literal corresponding to the bytes. The easiest way
+ * to do this is to use the ISO-8859-1 character set, which corresponds to
+ * the first 256 characters of the Unicode range. Protoc can then use

+/**
+ * Abstract interface implemented by Protocol Message objects.
+ *
+ * <p>This interface is implemented by all protocol message objects. Non-lite
+ * messages additionally implement the Message interface, which is a subclass
+ * of MessageLite. Use MessageLite instead when you only need the subset of
+ * features which it supports -- namely, nothing that uses descriptors or
+ * reflection. You can instruct the protocol compiler to generate classes
+ * which implement only MessageLite, not the full Message interface, by adding
+ * the follow line to the .proto file:
+ * <pre>
+ * option optimize_for = LITE_RUNTIME;
+ * </pre>
+ *
+ * <p>This is particularly useful on resource-constrained systems where the
+ * full protocol buffers runtime library is too big.
+ *
+ * <p>Note that on non-constrained systems (e.g. servers) when you need to link
+ * in lots of protocol definitions, a better way to reduce total code footprint
+ * is to use {@code optimize_for = CODE_SIZE}. This will make the generated
+ * code smaller while still supporting all the same features (at the expense of
+ * speed). {@code optimize_for = LITE_RUNTIME} is best when you only have a
+ * small number of message types linked into your binary, in which case the
+ * size of the protocol buffers runtime itself is the biggest problem.

+/**
+ * {@code RepeatedFieldBuilder} implements a structure that a protocol
+ * message uses to hold a repeated field of other protocol messages. It supports
+ * the classical use case of adding immutable {@link Message}'s to the
+ * repeated field and is highly optimized around this (no extra memory
+ * allocations and sharing of immutable arrays).
+ * <br>
+ * It also supports the additional use case of adding a {@link Message.Builder}
+ * to the repeated 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 SingleFieldBuilder} and {@code RepeatedFieldBuilder}
+ * 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

+ * 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 SingleFieldBuilder} and {@code RepeatedFieldBuilder}
+ * 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.

+/**
+ * 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}.

+ * <li>{@code java.io.StreamTokenizer}: This almost does what we want -- or,

+ * for one fatal flaw: It automatically un-escapes strings using Java
+ * escape sequences, which do not include all the escape sequences we

+ * <li>{@code java.util.Scanner}: This seems like a great way at least to
+ * parse regular expressions out of a stream (so we wouldn't have to load
+ * the entire input into a single string before parsing). Sadly,
+ * {@code Scanner} requires that tokens be delimited with some delimiter.
+ * Thus, although the text "foo:" should parse to two tokens ("foo" and
+ * ":"), {@code Scanner} would recognize it only as a single token.
+ * Furthermore, {@code Scanner} provides no way to inspect the contents
+ * of delimiters, making it impossible to keep track of line and column
+ * numbers.
+ * </ul>
+ *
+ * <p>Luckily, Java's regular expression support does manage to be useful to
+ * us. (Barely: We need {@code Matcher.usePattern()}, which is new in
+ * Java 1.5.) So, we can use that, at least. Unfortunately, this implies

+ * A set of low-level, high-performance static utility methods related

+ * outside of the core JDK libraries.
+ *
+ * <p>There are several variants of UTF-8. The one implemented by
+ * this class is the restricted definition of UTF-8 introduced in
+ * Unicode 3.1, which mandates the rejection of "overlong" byte
+ * sequences as well as rejection of 3-byte surrogate codepoint byte
+ * sequences. Note that the UTF-8 decoder included in Oracle's JDK
+ * has been modified to also reject "overlong" byte sequences, but (as
+ * of 2011) still accepts 3-byte surrogate codepoint byte sequences.
+ *
+ * <p>The byte sequences considered valid by this class are exactly
+ * those that can be roundtrip converted to Strings and back to bytes
+ * using the UTF-8 charset, without loss: <pre> {@code
+ * Arrays.equals(bytes, new String(bytes, Internal.UTF_8).getBytes(Internal.UTF_8))
+ * }</pre>
+ *
+ * <p>See the Unicode Standard,</br>
+ * Table 3-6. <em>UTF-8 Bit Distribution</em>,</br>
+ * Table 3-7. <em>Well Formed UTF-8 Byte Sequences</em>.
+ *
+ * <p>This class supports decoding of partial byte sequences, so that the
+ * bytes in a complete UTF-8 byte sequences can be stored in multiple
+ * segments. Methods typically return {@link #MALFORMED} if the partial
+ * byte sequence is definitely not well-formed, {@link #COMPLETE} if it is
+ * well-formed in the absence of additional input, or if the byte sequence
+ * apparently terminated in the middle of a character, an opaque integer
+ * "state" value containing enough information to decode the character when
