class lsst.pipe.base.PipelineDatasetTypes(initInputs: FrozenSet[DatasetType], initOutputs: FrozenSet[DatasetType], initIntermediates: FrozenSet[DatasetType], inputs: FrozenSet[DatasetType], prerequisites: FrozenSet[DatasetType], intermediates: FrozenSet[DatasetType], outputs: FrozenSet[DatasetType], byTask: Mapping[str, TaskDatasetTypes])

Bases: object

An immutable struct that classifies the dataset types used in a Pipeline.

Methods Summary

fromPipeline(pipeline, *, registry)

Extract and classify the dataset types from all tasks in a Pipeline.

Methods Documentation

classmethod fromPipeline(pipeline, *, registry: lsst.daf.butler.core.registry.Registry) → lsst.pipe.base.pipeline.PipelineDatasetTypes

Extract and classify the dataset types from all tasks in a Pipeline.

Parameters

pipeline: `Pipeline`

An ordered collection of tasks that can be run together.

registry: `Registry`

Registry used to construct normalized DatasetType objects and retrieve those that are incomplete.

Returns

types: `PipelineDatasetTypes`

The dataset types used by this Pipeline.

Raises

ValueError

Raised if Tasks are inconsistent about which datasets are marked prerequisite. This indicates that the Tasks cannot be run as part of the same Pipeline.
