public static final class Any.Builder extends GeneratedMessage.Builder<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);
}
// 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

      public static final Descriptors.Descriptor getDescriptor()

    • internalGetFieldAccessorTable

      protected GeneratedMessage.FieldAccessorTable internalGetFieldAccessorTable()
      Description copied from class: GeneratedMessage.Builder
      Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.
      Specified by:
      internalGetFieldAccessorTable in class GeneratedMessage.Builder<Any.Builder>

    • clear

      public Any.Builder clear()
      Description copied from class: GeneratedMessage.Builder
      Called by the initialization and clear code paths to allow subclasses to reset any of their builtin fields back to the initial values.
      Specified by:
      clear in interface Message.Builder
      Specified by:
      clear in interface MessageLite.Builder
      Overrides:
      clear in class GeneratedMessage.Builder<Any.Builder>

    • getDescriptorForType

      public Descriptors.Descriptor getDescriptorForType()
      Description copied from interface: Message.Builder
      Get the message's type's descriptor. See MessageOrBuilder.getDescriptorForType().
      Specified by:
      getDescriptorForType in interface Message.Builder
      Specified by:
      getDescriptorForType in interface MessageOrBuilder
      Overrides:
      getDescriptorForType in class GeneratedMessage.Builder<Any.Builder>

    • 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.

      getDefaultInstanceForType in interface MessageLiteOrBuilder
      Specified by:
      getDefaultInstanceForType in interface MessageOrBuilder

    • build

      public Any build()
      Description copied from interface: MessageLite.Builder
      Constructs the message based on the state of the Builder. Subsequent changes to the Builder will not affect the returned message.
      Specified by:
      build in interface Message.Builder
      Specified by:
      build in interface MessageLite.Builder

    • buildPartial

      public Any buildPartial()
      Description copied from interface: MessageLite.Builder
      Like MessageLite.Builder.build(), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned. Subsequent changes to the Builder will not affect the returned message.
      Specified by:
      buildPartial in interface Message.Builder

    • buildPartial0

      private void buildPartial0(Any result)

    • mergeFrom

      public Any.Builder mergeFrom(Message other)
      Description copied from interface: Message.Builder
      Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()).

      Merging occurs as follows. For each field:
      * For singular primitive fields, if the field is set in other, then other's value overwrites the value in this message.
      * For singular message fields, if the field is set in other, it is merged into the corresponding sub-message of this message using the same merging rules.
      * For repeated fields, the elements in other are concatenated with the elements in this message.
      * For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved.

      This is equivalent to the Message::MergeFrom method in C++.

      mergeFrom in class AbstractMessage.Builder<Any.Builder>

    • mergeFrom

    • isInitialized

      public final boolean isInitialized()
      Description copied from interface: MessageLiteOrBuilder

      isInitialized in interface MessageLiteOrBuilder
      Overrides:
      isInitialized in class GeneratedMessage.Builder<Any.Builder>

    • mergeFrom

      public Any.Builder mergeFrom(CodedInputStream input, ExtensionRegistryLite extensionRegistry) throws IOException
      Description copied from interface: MessageLite.Builder
      Like MessageLite.Builder.mergeFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.
      Specified by:
      mergeFrom in interface Message.Builder
      Specified by:
      mergeFrom in interface MessageLite.Builder

      Throws:
      IOException - an I/O error reading from the stream

    • 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.
      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
