This library has been updated to protobuf-2.4.1 as of 11/30/12.
Protocol Buffers (protobuf) source is available (via svn) at:
svn checkout http://protobuf.googlecode.com/svn/trunk/ protobuf-read-only
This code is covered under the BSD license (see COPYING.txt). Documentation is
available at http://code.google.com/p/protobuf.
This import includes only files in protobuf-lite, a lighter-weight library that
does not support reflection or descriptors. Manual changes include removing all
tests, testdata, config.h, and all files not used in protobuf-lite.

// Accessors
//
// Generated message classes include type-safe templated wrappers around
// these methods. Generally you should use those rather than call these
// directly, unless you are doing low-level memory management.
//
// When calling any of these accessors, the extension number requested
// MUST exist in the DescriptorPool provided to the constructor. Otheriwse,
// the method will fail an assert. Normally, though, you would not call
// these directly; you would either call the generated accessors of your
// message class (e.g. GetExtension()) or you would call the accessors
// of the reflection interface. In both cases, it is impossible to
// trigger this assert failure: the generated accessors only accept
// linked-in extension types as parameters, while the Reflection interface
// requires you to provide the FieldDescriptor describing the extension.
//
// When calling any of these accessors, a protocol-compiler-generated
// implementation of the extension corresponding to the number MUST
// be linked in, and the FieldDescriptor used to refer to it MUST be
// the one generated by that linked-in code. Otherwise, the method will
// die on an assert failure. The message objects returned by the message
// accessors are guaranteed to be of the correct linked-in type.
//
// These methods pretty much match Reflection except that:
// - They're not virtual.
// - They identify fields by number rather than FieldDescriptors.
// - They identify enum values using integers rather than descriptors.
// - Strings provide Mutable() in addition to Set() accessors.

// ===================================================================
// Glue for generated extension accessors
// -------------------------------------------------------------------
// Template magic
// First we have a set of classes representing "type traits" for different
// field types. A type traits class knows how to implement basic accessors
// for extensions of a particular type given an ExtensionSet. The signature
// for a type traits class looks like this:
//
// class TypeTraits {
// public:
// typedef ? ConstType;
// typedef ? MutableType;
//
// static inline ConstType Get(int number, const ExtensionSet& set);
// static inline void Set(int number, ConstType value, ExtensionSet* set);
// static inline MutableType Mutable(int number, ExtensionSet* set);
//
// // Variants for repeated fields.
// static inline ConstType Get(int number, const ExtensionSet& set,
// int index);
// static inline void Set(int number, int index,
// ConstType value, ExtensionSet* set);
// static inline MutableType Mutable(int number, int index,
// ExtensionSet* set);
// static inline void Add(int number, ConstType value, ExtensionSet* set);
// static inline MutableType Add(int number, ExtensionSet* set);
// };
//
// Not all of these methods make sense for all field types. For example, the
// "Mutable" methods only make sense for strings and messages, and the
// repeated methods only make sense for repeated types. So, each type
// traits class implements only the set of methods from this signature that it
// actually supports. This will cause a compiler error if the user tries to
// access an extension using a method that doesn't make sense for its type.
// For example, if "foo" is an extension of type "optional int32", then if you
// try to write code like:
// my_message.MutableExtension(foo)
// you will get a compile error because PrimitiveTypeTraits<int32> does not
// have a "Mutable()" method.
// -------------------------------------------------------------------
// PrimitiveTypeTraits
// Since the ExtensionSet has different methods for each primitive type,
// we must explicitly define the methods of the type traits class for each
// known type.

//
// This file contains the ZeroCopyInputStream and ZeroCopyOutputStream
// interfaces, which represent abstract I/O streams to and from which
// protocol buffers can be read and written. For a few simple
// implementations of these interfaces, see zero_copy_stream_impl.h.
//
// These interfaces are different from classic I/O streams in that they
// try to minimize the amount of data copying that needs to be done.
// To accomplish this, responsibility for allocating buffers is moved to
// the stream object, rather than being the responsibility of the caller.
// So, the stream can return a buffer which actually points directly into
// the final data structure where the bytes are to be stored, and the caller
// can interact directly with that buffer, eliminating an intermediate copy
// operation.
//
// As an example, consider the common case in which you are reading bytes
// from an array that is already in memory (or perhaps an mmap()ed file).
// With classic I/O streams, you would do something like:
// char buffer[BUFFER_SIZE];
// input->Read(buffer, BUFFER_SIZE);
// DoSomething(buffer, BUFFER_SIZE);
// Then, the stream basically just calls memcpy() to copy the data from
// the array into your buffer. With a ZeroCopyInputStream, you would do
// this instead:
// const void* buffer;
// int size;
// input->Next(&buffer, &size);
// DoSomething(buffer, size);
// Here, no copy is performed. The input stream returns a pointer directly
// into the backing array, and the caller ends up reading directly from it.
//
// If you want to be able to read the old-fashion way, you can create
// a CodedInputStream or CodedOutputStream wrapping these objects and use
// their ReadRaw()/WriteRaw() methods. These will, of course, add a copy
// step, but Coded*Stream will handle buffering so at least it will be
// reasonably efficient.
//
// ZeroCopyInputStream example:
// // Read in a file and print its contents to stdout.
// int fd = open("myfile", O_RDONLY);
// ZeroCopyInputStream* input = new FileInputStream(fd);
//
// const void* buffer;
// int size;
// while (input->Next(&buffer, &size)) {
// cout.write(buffer, size);
// }
//
// delete input;
// close(fd);
//
// ZeroCopyOutputStream example:
// // Copy the contents of "infile" to "outfile", using plain read() for
// // "infile" but a ZeroCopyOutputStream for "outfile".
// int infd = open("infile", O_RDONLY);
// int outfd = open("outfile", O_WRONLY);
// ZeroCopyOutputStream* output = new FileOutputStream(outfd);
//
// void* buffer;
// int size;
// while (output->Next(&buffer, &size)) {
// int bytes = read(infd, buffer, size);
// if (bytes < size) {
// // Reached EOF.
// output->BackUp(size - bytes);
// break;
// }
// }
//
// delete output;
// close(infd);

// Message interface, by adding the following line to the .proto file:
//
// option optimize_for = LITE_RUNTIME;
//
// This is particularly useful on resource-constrained systems where
// the full protocol buffers runtime library is too big.
//
// 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 optimize_for = CODE_SIZE. This
// will make the generated code smaller while still supporting all the
// same features (at the expense of speed). 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.

// Thread-safety in the Protocol Buffer library follows a simple rule:
// unless explicitly noted otherwise, it is always safe to use an object
// from multiple threads simultaneously as long as the object is declared
// const in all threads (or, it is only used in ways that would be allowed

// thread in a way that would not be allowed if it were const, then it is
// not safe to access that object in any other thread simultaneously.
//
// Put simply, read-only access to an object can happen in multiple threads
// simultaneously, but write access can only happen in a single thread at
// a time.
//
// The implementation does contain some "const" methods which actually modify
// the object behind the scenes -- e.g., to cache results -- but in these cases
// mutex locking is used to make the access thread-safe.

// This header is intended to be included only by internal .cc files and
// generated .pb.cc files. Users should not use this directly.
//
// This is basically a portable version of pthread_once().
//
// This header declares three things:
// * A type called ProtobufOnceType.
// * A macro GOOGLE_PROTOBUF_DECLARE_ONCE() which declares a variable of type
// ProtobufOnceType. This is the only legal way to declare such a variable.
// The macro may only be used at the global scope (you cannot create local
// or class member variables of this type).
// * A function GogoleOnceInit(ProtobufOnceType* once, void (*init_func)()).
// This function, when invoked multiple times given the same ProtobufOnceType
// object, will invoke init_func on the first call only, and will make sure
// none of the calls return before that first call to init_func has finished.
//
// This implements a way to perform lazy initialization. It's more efficient
// than using mutexes as no lock is needed if initialization has already
// happened.
//
// Example usage:
// void Init();
// GOOGLE_PROTOBUF_DECLARE_ONCE(once_init);
//
// // Calls Init() exactly once.
// void InitOnce() {
// GoogleOnceInit(&once_init, &Init);
// }
//
// Note that if GoogleOnceInit() is called before main() has begun, it must
// only be called by the thread that will eventually call main() -- that is,
// the thread that performs dynamic initialization. In general this is a safe
// assumption since people don't usually construct threads before main() starts,
// but it is technically not guaranteed. Unfortunately, Win32 provides no way
// whatsoever to statically-initialize its synchronization primitives, so our
// only choice is to assume that dynamic initialization is single-threaded.
