Class Any

  • All Implemented Interfaces:
    AnyOrBuilder, Message, MessageLite, MessageLiteOrBuilder, MessageOrBuilder, java.io.Serializable


    public final class Any
    extends com.google.protobuf.GeneratedMessageV3
    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"
         }

                                                   java.lang.String typeUrlPrefix)
        Packs a message using the given type URL prefix. The type URL will be constructed by concatenating the message type's full name to the prefix with an optional "/" separator if the prefix doesn't end with "/" already.
      • is

        public <T extends Message> boolean is(java.lang.Class<T> clazz)
      • getTypeUrl

        public java.lang.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.

        public ByteString getTypeUrlBytes()
         A URL/resource name that uniquely identifies the type of the serialized

         one "/" character. The last segment of the URL's path must represent

        public boolean equals(java.lang.Object obj)
        Description copied from interface: Message
        Compares the specified object with this message for equality. Returns true if the given object is a message of the same type (as defined by getDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheriting Object.equals() is incorrect.
        Specified by:
        equals in interface Message
        Overrides:
        equals in class AbstractMessage
        Parameters:

        Returns:
        true if the specified object is equal to this message
      • hashCode

        public int hashCode()
        Description copied from interface: Message
        Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheriting Object.hashCode() is incorrect.
        Specified by:
        hashCode in interface Message
        Overrides:
        hashCode in class AbstractMessage
        Returns:

      • toBuilder

      • getDefaultInstance

        public static Any getDefaultInstance()
      • getDefaultInstanceForType

        public Any getDefaultInstanceForType()
        Description copied from interface: MessageLiteOrBuilder
        Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.
