Method Details

node_list_signal(...)

source code 

node_list_signal is a signal, which is emitted, if a new list with nodes is retrieved. The signal has the URI of the service, the name of the service and a list with node names as parameter.

description_signal(...)

source code 

description_signal is a signal, which is emitted, if a new list with descriptions is retrieved. The signal has the URI of the service, the name of the service and a list with descriptions (multimaster_msgs_fkie.srv.ListDescription Response) parameter.

__init__(self)
(Constructor)

source code 

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__
(inherited documentation)

requestNodeList(self, service_uri, service, delay_exec=0.0)

source code 

This method starts a thread to get the informations about the default configured nodes. If all informations are retrieved, a node_list_signal of this class will be emitted. If for given service a thread is already running, the request will be ignored. This method is thread safe.

Parameters:
  • service_uri (str) - the URI of the service
  • service (str) - the name of service to get the node list
  • delay_exec (float) - delayd the execution

requestDescriptionList(self, service_uri, service, delay_exec=0.0)

source code 

This method starts a thread to get the descriptions from the default configuration node. If all informations are retrieved, a description_signal of this class will be emitted. If for given service a thread is already running, the request will be ignored. This method is thread safe.

Parameters:
  • service_uri (str) - the URI of the service
  • service (str) - the name of service to get the description
  • delay_exec (float) - delayd the execution
