ObjectLoader
An utility to load modules and objects in DIRAC and extensions, being sure that the extensions are considered
- class DIRAC.Core.Utilities.ObjectLoader.ObjectLoader(*args, **kwargs)
Bases:
objectClass for loading objects. Example:
from DIRAC.Core.Utilities.ObjectLoader import ObjectLoader ol = ObjectLoader() ol.loadObject(‘TransformationSystem.Client.TransformationClient’)
- __init__(baseModules=False)
init
- getObjects(modulePath, reFilter=None, parentClass=None, recurse=False, continueOnError=False)
Search for modules under a certain path
modulePath is the import string needed to access the parent module. Root modules will be included automatically (like DIRAC). For instance “ConfigurationSystem.Service”
reFilter is a regular expression to filter what to load. For instance “.*Handler” parentClass is a class object from which the loaded modules have to import from. For instance RequestHandler
- Parameters:
continueOnError – if True, continue loading further module even if one fails
- instance = <DIRAC.Core.Utilities.ObjectLoader.ObjectLoader object>
- loadModule(importString, hideExceptions=False)
Load a module from an import string
- loadObject(importString, objName=False, hideExceptions=False)
Load an object from inside a module
- reloadRootModules()
Retrigger the initialization of the rootModules.
This should be used with care. Currently, its only use is (and should stay) to retrigger the initialization after the CS has been fully initialized in LocalConfiguration.enableCS
- DIRAC.Core.Utilities.ObjectLoader.loadObjects(path, reFilter=None, parentClass=None)
Note: this does not work for editable install because it hardcodes DIRAC.__file__ It is better to use ObjectLoader().getObjects()
