Class Any
- All Implemented Interfaces:
AnyOrBuilder, Message, MessageLite, MessageLiteOrBuilder, MessageOrBuilder, Serializable
`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 }`.

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.

public int getSerializedSize()Description copied from interface:MessageLiteGet the number of bytes required to encode this message.

equals
Description copied from interface:MessageCompares the specified object with this message for equality. Returnstrueif the given object is a message of the same type (as defined bygetDescriptorForType()) and has identical values for all of its fields.

obj- object to be compared for equality with this message- Returns:
trueif the specified object is equal to this message
-
hashCode
public int hashCode()Description copied from interface:MessageReturns 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; inheritingObject.hashCode()is incorrect.- Specified by:
