Instance Variables | |
update_signal = Signal(MasterInfo) update_signal is a signal, which is emitted, if a new master_discovery_fkie.MasterInfo is retrieved. |
|
master_errors_signal = Signal(str, list) master_errors_signal is a signal (masteruri, list of errors), which is emitted, if we get a list with errors from remote master_discovery. |
|
error_signal = Signal(str, str) error_signal is a signal (masteruri, error message), which is emitted, if an error while retrieving a master info was occurred. |

Method Details |
This constructor should always be called with keyword arguments. Arguments are: *group* should be None; reserved for future extension when a ThreadGroup class is implemented. *target* is the callable object to be invoked by the run() method. Defaults to None, meaning nothing is called. *name* is the thread name. By default, a unique name is constructed of the form "Thread-N" where N is a small decimal number. *args* is the argument tuple for the target invocation. Defaults to (). *kwargs* is a dictionary of keyword arguments for the target invocation. Defaults to {}. If a subclass overrides the constructor, it must make sure to invoke the base class constructor (Thread.__init__()) before doing anything else to the thread.
|
Method representing the thread's activity. You may override this method in a subclass. The standard run() method invokes the callable object passed to the object's constructor as the target argument, if any, with sequential and keyword arguments taken from the args and kwargs arguments, respectively.
