Class Any

All Implemented Interfaces:
AnyOrBuilder, Message, MessageLite, MessageLiteOrBuilder, MessageOrBuilder, Serializable

public final class Any extends 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);
     }
     // or ...
     if (any.isSameTypeAs(Foo.getDefaultInstance())) {
       foo = any.unpack(Foo.getDefaultInstance());
     }

  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

    • 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. As of May 2023, there are no widely used type server
       implementations and no plans to implement one.
      
       Schemes other than `http`, `https` (or the empty scheme) might be
       used with implementation specific semantics.

    • 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

      public int getSerializedSize()
      Description copied from interface: MessageLite
      Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that. If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.

    • equals

      public boolean equals(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:
      obj - object to be compared for equality with this message
      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:
      the hash code value for this message

    • 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.
