Checks whether tasks in pipeline are correctly ordered.
Pipeline is correctly ordered if for any DatasetType produced by a task
in a pipeline all its consumer tasks are located after producer.
Parameters
----------
pipeline : `pipe.base.Pipeline`
Pipeline description.
taskFactory: `pipe.base.TaskFactory`, optional
Instance of an object which knows how to import task classes. It is only
used if pipeline task definitions do not define task classes.
Returns
-------
True for correctly ordered pipeline, False otherwise.
Raises
------
`ImportError` is raised when task class cannot be imported.
`DuplicateOutputError` is raised when there is more than one producer for a
dataset type.
`MissingTaskFactoryError` is raised when TaskFactory is needed but not
provided.

| def lsst.pipe.base.pipeTools.orderPipeline | ( | pipeline, | |
taskFactory = None |
|||
| ) |
Re-order tasks in pipeline to satisfy data dependencies.
When possible new ordering keeps original relative order of the tasks.
Parameters
----------
pipeline : `pipe.base.Pipeline`
Pipeline description.
taskFactory: `pipe.base.TaskFactory`, optional
Instance of an object which knows how to import task classes. It is only
used if pipeline task definitions do not define task classes.
Returns
-------
Correctly ordered pipeline (`pipe.base.Pipeline` instance).
Raises
------
`ImportError` is raised when task class cannot be imported.
`DuplicateOutputError` is raised when there is more than one producer for a
dataset type.
`PipelineDataCycleError` is also raised when pipeline has dependency cycles.
`MissingTaskFactoryError` is raised when TaskFactory is needed but not
provided.
