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

  • 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.

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)
Properties
private $options = NULL
 

The protocol buffer options.
