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