Protocol Implementation for Service clients over TCPROS

Instance Methods

__init__(self, resolved_name, service_class, headers=None, buff_size=65536)
ctor.

read_messages(self, b, msg_queue, sock)
In service implementation, reads in OK byte that preceeds each response.

Properties
Inherited from `object`: `__class__`

Method Details

init(self, resolved_name, service_class, headers=None, buff_size=65536)
(Constructor)

source code

ctor.

Parameters:

resolved_name (str) - resolved service name
service_class (Service) - Service data type class
headers (dict) - identifier for Service session
buff_size (int) - size of buffer (bytes) for reading responses from Service.

Overrides: object.__init__

get_header_fields(self)

source code

TCPROSTransportProtocol API

Returns: dict: {str : str}: header fields to send over connection
Overrides: tcpros_base.TCPROSTransportProtocol.get_header_fields

read_messages(self, b, msg_queue, sock)

source code

In service implementation, reads in OK byte that preceeds each response. The OK byte allows for the passing of error messages instead of a response message

Parameters:

b (StringIO) - buffer
msg_queue ([Message]) - Message queue to append to
sock (socket.socket) - socket to read from

Overrides: tcpros_base.TCPROSTransportProtocol.read_messages
