Declares an API Interface to be included in this interface. The including interface must redeclare all the methods from the included interface, but documentation and options are inherited as follows:

  • If after comment and whitespace stripping, the documentation string of the redeclared method is empty, it will be inherited from the original method.
  • Each annotation belonging to the service config (http, visibility) which is not set in the redeclared method will be inherited.
  • If an http annotation is inherited, the path pattern will be modified as follows. Any version prefix will be replaced by the version of the including interface plus the [root][] path if specified. Example of a simple mixin: package google.acl.v1; service AccessControl { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v1/{resource=}:getAcl"; } } package google.storage.v2; service Storage { rpc GetAcl(GetAclRequest) returns (Acl); // Get a data record. rpc GetData(GetDataRequest) returns (Data) { option (google.api.http).get = "/v2/{resource=}"; } } Example of a mixin configuration: apis:
    • name: google.storage.v2.Storage mixins:
      • name: google.acl.v1.AccessControl The mixin construct implies that all methods in AccessControl are also declared with same name and request/response types in Storage. A documentation generator or annotation processor will see the effective Storage.GetAcl method after inheriting documentation and annotations as follows: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/{resource=**}:getAcl"; } ... } Note how the version in the path pattern changed from v1 to v2. If the root field in the mixin is specified, it should be a relative path under which inherited HTTP paths are placed. Example: apis:
    • name: google.storage.v2.Storage mixins:
      • name: google.acl.v1.AccessControl root: acls This implies the following inherited HTTP annotation: service Storage { // Get the underlying ACL object. rpc GetAcl(GetAclRequest) returns (Acl) { option (google.api.http).get = "/v2/acls/{resource=**}:getAcl"; } ... }

Methods
public __construct( $data = NULL)
 

Constructor.

  • param array $data { Optional. Data for populating the Message object.
    @type string $name
          The fully qualified name of the interface which is included.
    @type string $root
          If non-empty specifies a path under which inherited HTTP paths
          are rooted.

  • ignore
public Google\Protobuf\Internal\Message::clear()
 

Clear all containing fields.

  • return null
public Google\Protobuf\Internal\Message::discardUnknownFields()
 

Clear all unknown fields previously parsed.

  • return null
public getName()
 

The fully qualified name of the interface which is included.

If non-empty specifies a path under which inherited HTTP paths are rooted.

public Google\Protobuf\Internal\Message::jsonByteSize( $options = 0)
 
  • ignore
public Google\Protobuf\Internal\Message::mergeFrom( $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.

  • param object $msg Protobuf message to be merged from.
  • return null
public Google\Protobuf\Internal\Message::mergeFromJsonString( $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.

  • param string $data Json protobuf data.
  • param bool $ignore_unknown
  • return null
  • throws \Exception Invalid data.
public Google\Protobuf\Internal\Message::mergeFromString( $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.

  • param string $data Binary protobuf data.
  • return null
  • throws \Exception Invalid data.
public Google\Protobuf\Internal\Message::parseFromJsonStream( $input, $ignore_unknown)
 
  • ignore
public Google\Protobuf\Internal\Message::parseFromStream( $input)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToJsonStream( $output)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToJsonString( $options = 0)
 

Serialize the message to json string.

  • return string Serialized json protobuf data.
public Google\Protobuf\Internal\Message::serializeToStream( $output)
 
  • ignore
public Google\Protobuf\Internal\Message::serializeToString()
 

Serialize the message to string.

  • return string Serialized binary protobuf data.
public setName(string $var)
 

The fully qualified name of the interface which is included.

Generated from protobuf field string name = 1;

  • param string $var
  • return $this
public setRoot(string $var)
 

If non-empty specifies a path under which inherited HTTP paths are rooted.

Generated from protobuf field string root = 2;

  • param string $var
  • return $this
Properties
protected $name = ''
 

The fully qualified name of the interface which is included.

Generated from protobuf field string name = 1;

protected $root = ''
 

If non-empty specifies a path under which inherited HTTP paths are rooted.

Generated from protobuf field string root = 2;

Methods
protected Google\Protobuf\Internal\Message::hasOneof( $number)
protected Google\Protobuf\Internal\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.

  • param array $array An array containing message properties and values.
  • return null
protected Google\Protobuf\Internal\Message::mergeFromJsonArray( $array, $ignore_unknown)
protected Google\Protobuf\Internal\Message::readOneof( $number)
protected Google\Protobuf\Internal\Message::readWrapperValue( $member)
protected Google\Protobuf\Internal\Message::whichOneof( $oneof_name)
protected Google\Protobuf\Internal\Message::writeOneof( $number, $value)
protected Google\Protobuf\Internal\Message::writeWrapperValue( $member, $value)
