Method Details

[hide private]

init(self, noopts=0, keeproot=False, name=None)
(Constructor)

source code

Initializer that takes care of basic daemon options. Creates a PID file.

Overrides: ZenUtils.CmdBase.CmdBase.__init__

gotPerspective(self, perspective)

source code

This gets called every time we reconnect.

Parameters:

perspective (Twisted perspective object) - Twisted perspective object

getService(self, serviceName, serviceListeningInterface=None)

source code

Attempt to get a service from zenhub. Returns a deferred. When service is retrieved it is stashed in self.services with serviceName as the key. When getService is called it will first check self.services and if serviceName is already there it will return the entry from self.services wrapped in a defer.succeed
