https://developers.google.com/protocol-buffers/protobuf-java/: Core Protocol Buffers library. Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. 
// Generated by the protocol buffer compiler.  DO NOT EDIT!
// source: google/protobuf/any.proto

package com.google.protobuf;


`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 := ptypes.MarshalAny(foo)
     ...
     foo := &pb.Foo{}
     if err := ptypes.UnmarshalAny(any, 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"
    }

 *     ...
 *     if (any.UnpackTo(&amp;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.

 * JSON
 * ====
 * The JSON representation of an `Any` value uses the regular
 * representation of the deserialized, embedded message, with an
 * additional field `&#64;type` which contains the type URL. Example:
 *     package google.profile;
 *     message Person {
 *       string first_name = 1;
 *       string last_name = 2;
 *     }

 *       "firstName": &lt;string&gt;,
 *       "lastName": &lt;string&gt;
 *     }

`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 := ptypes.MarshalAny(foo)
     ...
     foo := &pb.Foo{}
     if err := ptypes.UnmarshalAny(any, 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 
/**
   * <pre>
   * `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(&amp;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 := &amp;pb.Foo{...}
   *      any, err := ptypes.MarshalAny(foo)
   *      ...
   *      foo := &amp;pb.Foo{}
   *      if err := ptypes.UnmarshalAny(any, 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 `&#64;type` which contains the type URL. Example:
   *     package google.profile;
   *     message Person {
   *       string first_name = 1;
   *       string last_name = 2;
   *     }
   *     {
   *       "&#64;type": "type.googleapis.com/google.profile.Person",
   *       "firstName": &lt;string&gt;,
   *       "lastName": &lt;string&gt;
   *     }
   * 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 `&#64;type`
   * field. Example (for message [google.protobuf.Duration][]):
   *     {
   *       "&#64;type": "type.googleapis.com/google.protobuf.Duration",
   *       "value": "1.212s"
   *     }
   * </pre>
   *
   * Protobuf type {@code google.protobuf.Any}

In practice, teams usually precompile into the binary all types that they

scheme `http`, `https`, or no scheme, one can optionally set up a type
server that maps type URLs to message definitions as follows:

 * 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

Schemes other than `http`, `https` (or the empty scheme) might be

     * (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.
