Protocol buffer representations of descriptors.

This file defines a set of protocol message classes which represent the same information represented by the classes defined in descriptor.h. You can convert a FileDescriptorProto to a FileDescriptor using the DescriptorPool class. Thus, the classes in this file allow protocol type definitions to be communicated efficiently between processes.

The protocol compiler currently doesn't support auto-generated documentation, hence this page contains no descriptions. This file was generated by the protocol compiler from descriptor.proto, whose contents are as follows:

// Options

// Each of the definitions above may have "options" attached.  These are
// just annotations which may cause code to be generated slightly differently
// or may contain hints for code that manipulates protocol messages.
//
// Clients may define custom options as extensions of the *Options messages.
// These extensions may not yet be known at parsing time, so the parser cannot
// store the values in them.  Instead it stores them in a field in the *Options
// message called uninterpreted_option. This field must have the same name
// across all *Options messages. We then use this field to populate the
// extensions when we build a descriptor, at which point all protos have been
// parsed and so all extensions are known.
//
// Extension numbers for custom options may be chosen as follows:
// * For options which will only be used within a single application or
//   organization, or for experimental options, use field numbers 50000
//   through 99999.  It is up to you to ensure that you do not use the
//   same number for multiple options.
// * For options which will be published and used publicly by multiple
//   independent entities, e-mail protobuf-global-extension-registry@google.com
//   to reserve extension numbers. Simply provide your project name (e.g.
//   Objective-C plugin) and your project website (if available) -- there's no
//   need to explain how you intend to use them. Usually you only need one
//   extension number. You can declare multiple options with only one extension
//   number by putting them in a sub-message. See the Custom Options section of
//   the docs for examples:
//   https://developers.google.com/protocol-buffers/docs/proto#options
//   If this turns out to be popular, a web service will be set up
//   to automatically assign option numbers.

  // A Location identifies a piece of source code in a .proto file which
  // corresponds to a particular definition.  This information is intended
  // to be useful to IDEs, code indexers, documentation generators, and similar
  // tools.
  //
  // For example, say we have a file like:
  //   message Foo {
  //     optional string foo = 1;
  //   }
  // Let's look at just the field definition:
  //   optional string foo = 1;
  //   ^       ^^     ^^  ^  ^^^
  //   a       bc     de  f  ghi
  // We have the following locations:
  //   span   path               represents
  //   [[]a,i)  [[] 4, 0, 2, 0 ]     The whole field definition.
  //   [[]a,b)  [[] 4, 0, 2, 0, 4 ]  The label (optional).
  //   [[]c,d)  [[] 4, 0, 2, 0, 5 ]  The type (string).
  //   [[]e,f)  [[] 4, 0, 2, 0, 1 ]  The name (foo).
  //   [[]g,h)  [[] 4, 0, 2, 0, 3 ]  The number (1).
  //
  // Notes:
  // - A location may refer to a repeated field itself (i.e. not to any
  //   particular index within it).  This is used whenever a set of elements are
  //   logically enclosed in a single code segment.  For example, an entire
  //   extend block (possibly containing multiple extension definitions) will
  //   have an outer location whose path refers to the "extensions" repeated
  //   field without an index.
  // - Multiple locations may have the same path.  This happens when a single
  //   logical declaration is spread out across multiple places.  The most
  //   obvious example is the "extend" block again -- there may be multiple
  //   extend blocks in the same scope, each of which will have the same path.
  // - A location's span is not always a subset of its parent's span.  For
  //   example, the "extendee" of an extension declaration appears at the
  //   beginning of the "extend" block and is shared by all extensions within
  //   the block.
  // - Just because a location's span is a subset of some other location's span
  //   does not mean that it is a descendant.  For example, a "group" defines
  //   both a type and a field in a single declaration.  Thus, the locations
  //   corresponding to the type and field and their components will overlap.
  // - Code which tries to interpret locations should probably be designed to
  //   ignore those that it doesn't understand, as more types of locations could
  //   be recorded in the future.
  repeated Location location = 1;
  message Location {
    // Identifies which part of the FileDescriptorProto was defined at this
    // location.
    //
    // Each element is a field number or an index.  They form a path from

    // example, this path:
    //   [[] 4, 3, 2, 7, 1 ]
    // refers to:
    //   file.message_type(3)  // 4, 3
    //       .field(7)         // 2, 7
    //       .name()           // 1
    // This is because FileDescriptorProto.message_type has field number 4:
    //   repeated DescriptorProto message_type = 4;
    // and DescriptorProto.field has field number 2:
    //   repeated FieldDescriptorProto field = 2;
    // and FieldDescriptorProto.name has field number 1:
    //   optional string name = 1;
    //
    // Thus, the above path gives the location of a field name.  If we removed
