Method Details

Parameters:: options - the optparse option instance of command-line options
(type=dict); socketPath - the path of the Unix domain socket for PB
(type=str); brain - a reference to the worker brain
(type=WorkerBrain)

This will spawn a new flumotion-job process.

Parameters:: avatarId - avatarId the component should use to log in

(type=str); moduleName - name of the module to create the component from
(type=str); methodName - the factory method to use to create the component
(type=str); nice - nice level
(type=int); bundles - ordered list of (bundleName, bundlePath) for this component
