- "description": "`Any` contains an arbitrary serialized protocol buffer message along with a\nURL that describes the type of the serialized message.\n\nProtobuf library provides support to pack/unpack Any values in the form\nof utility functions or additional generated methods of the Any type.\n\nExample 1: Pack and unpack a message in C++.\n\n Foo foo = ...;\n Any any;\n any.PackFrom(foo);\n ...\n if (any.UnpackTo(\u0026foo)) {\n ...\n }\n\nExample 2: Pack and unpack a message in Java.\n\n Foo foo = ...;\n Any any = Any.pack(foo);\n ...\n if (any.is(Foo.class)) {\n foo = any.unpack(Foo.class);\n }\n\n Example 3: Pack and unpack a message in Python.\n\n foo = Foo(...)\n any = Any()\n any.Pack(foo)\n ...\n if any.Is(Foo.DESCRIPTOR):\n any.Unpack(foo)\n ...\n\n Example 4: Pack and unpack a message in Go\n\n foo := \u0026pb.Foo{...}\n any, err := ptypes.MarshalAny(foo)\n ...\n foo := \u0026pb.Foo{}\n if err := ptypes.UnmarshalAny(any, foo); err != nil {\n ...\n }\n\nThe pack methods provided by protobuf library will by default use\n'type.googleapis.com/full.type.name' as the type URL and the unpack\nmethods only use the fully qualified type name after the last '/'\nin the type URL, for example \"foo.bar.com/x/y.z\" will yield type\nname \"y.z\".\n\n\nJSON\n====\nThe JSON representation of an `Any` value uses the regular\nrepresentation of the deserialized, embedded message, with an\nadditional field `@type` which contains the type URL. Example:\n\n package google.profile;\n message Person {\n string first_name = 1;\n string last_name = 2;\n }\n\n {\n \"@type\": \"type.googleapis.com/google.profile.Person\",\n \"firstName\": \u003cstring\u003e,\n \"lastName\": \u003cstring\u003e\n }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n {\n \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n \"value\": \"1.212s\"\n }"
