  38. // `Any` contains an arbitrary serialized protocol buffer message along with a

  40. //
  41. // Protobuf library provides support to pack/unpack Any values in the form
  42. // of utility functions or additional generated methods of the Any type.
  43. //
  44. // Example 1: Pack and unpack a message in C++.
  45. //
  46. // Foo foo = ...;
  47. // Any any;
  48. // any.PackFrom(foo);
  49. // ...
  50. // if (any.UnpackTo(&foo)) {
  51. // ...
  52. // }
  53. //
  54. // Example 2: Pack and unpack a message in Java.
  55. //
  56. // Foo foo = ...;
  57. // Any any = Any.pack(foo);
  58. // ...
  59. // if (any.is(Foo.class)) {
  60. // foo = any.unpack(Foo.class);
  61. // }
  62. // // or ...
  63. // if (any.isSameTypeAs(Foo.getDefaultInstance())) {
  64. // foo = any.unpack(Foo.getDefaultInstance());
  65. // }
  66. //
  67. // Example 3: Pack and unpack a message in Python.
  68. //
  69. // foo = Foo(...)
  70. // any = Any()
  71. // any.Pack(foo)
  72. // ...
  73. // if any.Is(Foo.DESCRIPTOR):
  74. // any.Unpack(foo)
  75. // ...
  76. //
  77. // Example 4: Pack and unpack a message in Go
  78. //
  79. // foo := &pb.Foo{...}
  80. // any, err := anypb.New(foo)
  81. // if err != nil {
  82. // ...
  83. // }
  84. // ...
  85. // foo := &pb.Foo{}
  86. // if err := any.UnmarshalTo(foo); err != nil {
  87. // ...
  88. // }
  89. //
  90. // The pack methods provided by protobuf library will by default use
  91. // 'type.googleapis.com/full.type.name' as the type URL and the unpack
  92. // methods only use the fully qualified type name after the last '/'
  93. // in the type URL, for example "foo.bar.com/x/y.z" will yield type
  94. // name "y.z".
  95. //
  96. // JSON
  97. //
  98. // The JSON representation of an `Any` value uses the regular
  99. // representation of the deserialized, embedded message, with an
  100. // additional field `@type` which contains the type URL. Example:
  101. //
  102. // package google.profile;
  103. // message Person {
  104. // string first_name = 1;
  105. // string last_name = 2;
  106. // }
  107. //
  108. // {
  109. // "@type": "type.googleapis.com/google.profile.Person",
  110. // "firstName": <string>,
  111. // "lastName": <string>
  112. // }
  113. //
  114. // If the embedded message type is well-known and has a custom JSON
  115. // representation, that representation will be embedded adding a field
  116. // `value` which holds the custom JSON in addition to the `@type`
  117. // field. Example (for message [google.protobuf.Duration][]):
  118. //
  119. // {
  120. // "@type": "type.googleapis.com/google.protobuf.Duration",
  121. // "value": "1.212s"
  122. // }
  123. //
  124. message Any {
  125. // A URL/resource name that uniquely identifies the type of the serialized
  126. // protocol buffer message. This string must contain at least
  127. // one "/" character. The last segment of the URL's path must represent
  128. // the fully qualified name of the type (as in
  129. // `path/google.protobuf.Duration`). The name should be in a canonical form
  130. // (e.g., leading "." is not accepted).
  131. //
  132. // In practice, teams usually precompile into the binary all types that they
  133. // expect it to use in the context of Any. However, for URLs which use the
  134. // scheme `http`, `https`, or no scheme, one can optionally set up a type
  135. // server that maps type URLs to message definitions as follows:
  136. //
  137. // * If no scheme is provided, `https` is assumed.
  138. // * An HTTP GET on the URL must yield a [google.protobuf.Type][]
  139. // value in binary format, or produce an error.
  140. // * Applications are allowed to cache lookup results based on the
  141. // URL, or have them precompiled into a binary to avoid any
  142. // lookup. Therefore, binary compatibility needs to be preserved
  143. // on changes to types. (Use versioned type names to manage
  144. // breaking changes.)
  145. //
  146. // Note: this functionality is not currently available in the official
  147. // protobuf release, and it is not used for type URLs beginning with
  148. // type.googleapis.com.
  149. //
  150. // Schemes other than `http`, `https` (or the empty scheme) might be
  151. // used with implementation specific semantics.
  152. //
  153. string type_url = 1;
  154. // Must be a valid serialized protocol buffer of the above specified type.
