TaskDef

class lsst.pipe.base.TaskDef(taskName, config, taskClass=None, label='')

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

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.

config : lsst.pex.config.Config

Instance of the configuration class corresponding to this task class, usually with all overrides applied. This config will be frozen.

taskClass : type or None

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.
