@Generated public final class Any extends GeneratedMessage implements AnyOrBuilder
`Any` contains an arbitrary serialized protocol buffer message along with a
URL that describes the type of the serialized message.

In its binary encoding, an `Any` is an ordinary message; but in other wire
forms like JSON, it has a special encoding. The format of the type URL is
described on the `type_url` field.

Protobuf APIs provide utilities to interact with `Any` values:

- A 'pack' operation accepts a message and constructs a generic `Any` wrapper
around it.
- An 'unpack' operation reads the content of an `Any` message, either into an
existing message or a new one. Unpack operations must check the type of the
value they unpack against the declared `type_url`.
- An 'is' operation decides whether an `Any` contains a message of the given
type, i.e. whether it can 'unpack' that type.

The JSON format representation of an `Any` follows one of these cases:

- For types without special-cased JSON encodings, the JSON format
representation of the `Any` is the same as that of the message, with an
additional `@type` field which contains the type URL.
- For types with special-cased JSON encodings (typically called 'well-known'
types, listed in https://protobuf.dev/programming-guides/json/#any), the
JSON format representation has a key `@type` which contains the type URL
and a key `value` which contains the JSON-serialized value.

The text format representation of an `Any` is like a message with one field
whose name is the type URL in brackets. For example, an `Any` containing a
`foo.Bar` message may be written `[type.googleapis.com/foo.Bar] { a: 2 }`.

      public Descriptors.Descriptor getDescriptorForType()
      Description copied from interface: MessageOrBuilder
      Get the message's type's descriptor. This differs from the getDescriptor() method of generated message classes in that this method is an abstract method of the Message interface whereas getDescriptor() is a static method of a specific class. They return the same thing.

    • internalGetFieldAccessorTable

      protected GeneratedMessage.FieldAccessorTable internalGetFieldAccessorTable()
      Description copied from class: GeneratedMessage
      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.

    • getTypeUrl

      public String getTypeUrl()
      Identifies the type of the serialized Protobuf message with a URI reference
consisting of a prefix ending in a slash and the fully-qualified type name.

Example: type.googleapis.com/google.protobuf.StringValue

This string must contain at least one `/` character, and the content after
the last `/` must be the fully-qualified name of the type in canonical
form, without a leading dot. Do not write a scheme on these URI references
so that clients do not attempt to contact them.

The prefix is arbitrary and Protobuf implementations are expected to
simply strip off everything up to and including the last `/` to identify
the type. `type.googleapis.com/` is a common default prefix that some
legacy implementations require. This prefix does not indicate the origin of
the type, and URIs containing it are not expected to respond to any
requests.

All type URL strings must be legal URI references with the additional
restriction (for the text format) that the content of the reference
must consist only of alphanumeric characters, percent-encoded escapes, and
characters in the following set (not including the outer backticks):
`/-.~_!$&()*+,;=`. Despite our allowing percent encodings, implementations
should not unescape them to prevent confusion with existing parsers. For
example, `type.googleapis.com%2FFoo` should be rejected.

In the original design of `Any`, the possibility of launching a type
resolution service at these type URLs was considered but Protobuf never
implemented one and considers contacting these URLs to be problematic and
a potential security issue. Do not attempt to contact type URLs.
      string type_url = 1;
      Specified by:
      getTypeUrl in interface AnyOrBuilder
      Returns:
      The typeUrl.

    • getTypeUrlBytes

      public ByteString getTypeUrlBytes()
      Identifies the type of the serialized Protobuf message with a URI reference
consisting of a prefix ending in a slash and the fully-qualified type name.

      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.
