Any
class Any extends AnyBase (View source)
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 := 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": 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"
}

Methods
Constructor.
Merges the contents of the specified message into current message.
Parses a json string to protobuf message.
Populates the message from a user-supplied PHP array. Array keys correspond to Message properties and nested message properties.
This method will try to resolve the type_url in Any message to get the targeted message type. If failed, an error will be thrown. Otherwise, the method will create a message of the targeted type and fill it with the decoded value in Any.
The type_url will be created according to the given message’s type and the value is encoded data from the given message.
This method returns whether the type_url in any_message is corresponded to the given class.
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).

clear()
Clear all containing fields.
discardUnknownFields()
Clear all unknown fields previously parsed.
mergeFrom(object $msg)
Merges the contents of the specified message into current message.
This method merges the contents of the specified message into the current message. Singular fields that are set in the specified message overwrite the corresponding fields in the current message. Repeated fields are appended. Map fields key-value pairs are overwritten. Singular/Oneof sub-messages are recursively merged. All overwritten sub-messages are deep-copied.
mergeFromString(string $data)
Parses a protocol buffer contained in a string.
This function takes a string in the (non-human-readable) binary wire format, matching the encoding output by serializeToString(). See mergeFrom() for merging behavior, if the field is already set in the specified message.
mergeFromJsonString(string $data, $ignore_unknown = false)
Parses a json string to protobuf message.
This function takes a string in the json wire format, matching the encoding output by serializeToJsonString(). See mergeFrom() for merging behavior, if the field is already set in the specified message.

mergeFromArray(array $array)
Populates the message from a user-supplied PHP array. Array keys correspond to Message properties and nested message properties.
Example:
$message->mergeFromArray([
'name' => 'This is a message name',
'interval' => [
'startTime' => time() - 60,
'endTime' => time(),
]
]);This method will trigger an error if it is passed data that cannot be converted to the correct type. For example, a StringValue field must receive data that is either a string or a StringValue object.

unpack()
This method will try to resolve the type_url in Any message to get the targeted message type. If failed, an error will be thrown. Otherwise, the method will create a message of the targeted type and fill it with the decoded value in Any.
pack($msg)
The type_url will be created according to the given message’s type and the value is encoded data from the given message.
.
is($klass)
This method returns whether the type_url in any_message is corresponded to the given class.
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,
httpsis 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.

setTypeUrl(string $var)
