registerPackagePath(self, packagePath, key, prefix='flumotion')

source code 

Register a given path as a path that can be imported from. Used to support partition of bundled code or import code from various uninstalled location.

sys.path will also be changed to include this, and remove references to older packagePath's for the same bundle.

Parameters:
  • packagePath (string @param key a unique id for the package being registered) - path to add under which the module namespaces live, (ending in an md5sum, for flumotion purposes)
  • prefix (string) - prefix of the packages to be considered
  • key (string)
