Package com.google.protobuf

Class Any

  • All Implemented Interfaces:
    AnyOrBuilder, MessageLite, MessageLiteOrBuilder
    public final class Any
extends GeneratedMessageLite<Any,​Any.Builder>
implements AnyOrBuilder
     `Any` contains an arbitrary serialized protocol buffer message along with a
 URL that describes the type of the serialized message.
 Protobuf library provides support to pack/unpack Any values in the form
 of utility functions or additional generated methods of the Any type.
 Example 1: Pack and unpack a message in C++.
     Foo foo = ...;
     Any any;
     any.PackFrom(foo);
     ...
     if (any.UnpackTo(&foo)) {
       ...
     }
 Example 2: Pack and unpack a message in Java.
     Foo foo = ...;
     Any any = Any.pack(foo);
     ...
     if (any.is(Foo.class)) {
       foo = any.unpack(Foo.class);
     }
 Example 3: Pack and unpack a message in Python.
     foo = Foo(...)
     any = Any()
     any.Pack(foo)
     ...
     if any.Is(Foo.DESCRIPTOR):
       any.Unpack(foo)
       ...
 Example 4: Pack and unpack a message in Go
      foo := &pb.Foo{...}
      any, err := anypb.New(foo)
      if err != nil {
        ...
      }
      ...
      foo := &pb.Foo{}
      if err := any.UnmarshalTo(foo); err != nil {
        ...
      }
 The pack methods provided by protobuf library will by default use
 'type.googleapis.com/full.type.name' as the type URL and the unpack
 methods only use the fully qualified type name after the last '/'
 in the type URL, for example "foo.bar.com/x/y.z" will yield type
 name "y.z".
 JSON
 The JSON representation of an `Any` value uses the regular
 representation of the deserialized, embedded message, with an
 additional field `@type` which contains the type URL. Example:
     package google.profile;
     message Person {
       string first_name = 1;
       string last_name = 2;
     }
     {
       "@type": "type.googleapis.com/google.profile.Person",
       "firstName": <string>,
       "lastName": <string>
     }
 If the embedded message type is well-known and has a custom JSON
 representation, that representation will be embedded adding a field
 `value` which holds the custom JSON in addition to the `@type`
 field. Example (for message [google.protobuf.Duration][]):
     {
       "@type": "type.googleapis.com/google.protobuf.Duration",
       "value": "1.212s"
     }
    Protobuf type google.protobuf.Any

    • Method Detail

      • getTypeUrl

        public String getTypeUrl()
         A URL/resource name that uniquely identifies the type of the serialized
 protocol buffer message. This string must contain at least
 one "/" character. The last segment of the URL's path must represent
 the fully qualified name of the type (as in
 `path/google.protobuf.Duration`). The name should be in a canonical form
 (e.g., leading "." is not accepted).
 In practice, teams usually precompile into the binary all types that they
 expect it to use in the context of Any. However, for URLs which use the
 scheme `http`, `https`, or no scheme, one can optionally set up a type
 server that maps type URLs to message definitions as follows:
 * If no scheme is provided, `https` is assumed.
 * An HTTP GET on the URL must yield a [google.protobuf.Type][]
   value in binary format, or produce an error.
 * Applications are allowed to cache lookup results based on the
   URL, or have them precompiled into a binary to avoid any
   lookup. Therefore, binary compatibility needs to be preserved
   on changes to types. (Use versioned type names to manage
   breaking changes.)
 Note: this functionality is not currently available in the official
 protobuf release, and it is not used for type URLs beginning with
 type.googleapis.com.
 Schemes other than `http`, `https` (or the empty scheme) might be
 used with implementation specific semantics.
        string type_url = 1;
        Specified by:
        getTypeUrl in interface AnyOrBuilder
        Returns:
        The typeUrl.

      • getTypeUrlBytes

        public ByteString getTypeUrlBytes()
         A URL/resource name that uniquely identifies the type of the serialized
 protocol buffer message. This string must contain at least
 one "/" character. The last segment of the URL's path must represent
 the fully qualified name of the type (as in
 `path/google.protobuf.Duration`). The name should be in a canonical form
 (e.g., leading "." is not accepted).

        getTypeUrlBytes in interface AnyOrBuilder
        Returns:
        The bytes for typeUrl.

      • getValue

        public ByteString getValue()
         Must be a valid serialized protocol buffer of the above specified type.
        bytes value = 2;
        Specified by:
        getValue in interface AnyOrBuilder
        Returns:
        The value.

                                     Object arg1)
        Description copied from class: GeneratedMessageLite
        A method that implements different types of operations described in GeneratedMessageLite.MethodToInvoke. These different kinds of operations are required to implement message-level operations for builders in the runtime. This method bundles those operations to reduce the generated methods count.
        • NEW_INSTANCE returns a new instance of the protocol buffer that has not yet been made immutable. See MAKE_IMMUTABLE.
        • IS_INITIALIZED returns null for false and the default instance for true. It doesn't use or modify any memoized value.
        • GET_MEMOIZED_IS_INITIALIZED returns the memoized isInitialized byte value.
        • SET_MEMOIZED_IS_INITIALIZED sets the memoized isInitialized byte value to 1 if the first parameter is not null, or to 0 if the first parameter is null.
        • NEW_BUILDER returns a BuilderType instance.
        This method, plus the implementation of the Builder, enables the Builder class to be proguarded away entirely on Android.

        For use by generated code only.
