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);
     }
  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"
     }

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.
 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
 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).

bytes value = 2;

Specified by:

getValue in interface AnyOrBuilder

The value.

isInitialized

public final boolean isInitialized()

Specified by:

isInitialized in interface MessageLiteOrBuilder

Overrides:

isInitialized in class GeneratedMessageV3

writeTo

public void writeTo(CodedOutputStream output)
             throws IOException

Description copied from interface: MessageLite

Serializes the message and writes it to output. This does not flush or close the stream.

Specified by:

writeTo in interface MessageLite

Overrides:

writeTo in class GeneratedMessageV3

Throws:

IOException

getSerializedSize

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.

Specified by:

getSerializedSize in interface MessageLite

Overrides:

getSerializedSize in class GeneratedMessageV3

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.
