__init__(self)

source code

stop(self)

source code

requestNodeList(self, service_uri, service, delay_exec=0.0)
This method starts a thread to get the informations about the default configured nodes.

source code

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

Class Variables
	node_list_signal = `Signal(str, str, list)` node_list_signal is a signal, which is emitted, if a new list with nodes is retrieved.
	description_signal = `Signal(str, str, list)` description_signal is a signal, which is emitted, if a new list with descriptions is retrieved.
	err_signal = `Signal(str, str, str)`

Method Details

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

Value:

Signal(str, str, list)

description_signal

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.
