TaskDef

class lsst.pipe.base.TaskDef(taskName: Optional[str] = None, config: Optional[Config] = None, taskClass: Optional[Type[PipelineTask]] = None, label: Optional[str] = None)

Bases: object

TaskDef is a collection of information about task needed by Pipeline.

The information includes task name, configuration object and optional task class. This class is just a collection of attributes and it exposes all of them so that attributes could potentially be modified in place (e.g. if configuration needs extra overrides).

Attributes:

taskName : str, optional

PipelineTask class name, currently it is not specified whether this is a fully-qualified name or partial name (e.g. module.TaskClass). Framework should be prepared to handle all cases. If not provided, taskClass must be, and taskClass.__name__ is used.

config : lsst.pex.config.Config, optional

Instance of the configuration class corresponding to this task class, usually with all overrides applied. This config will be frozen. If not provided, taskClass must be provided and taskClass.ConfigClass() will be used.

taskClass : type, optional

PipelineTask class object, can be None. If None then framework will have to locate and load class.

label : str, optional

Task label, usually a short string unique in a pipeline. If not provided, taskClass must be, and taskClass._DefaultName will be used.
