DatasetKey¶

class lsst.pipe.base.quantum_graph_skeleton.DatasetKey(parent_dataset_type_name: str, data_id_values: tuple[int | str | None, ...])¶

Identifier type for dataset keys in a QuantumGraphSkeleton.

Attributes Summary

`data_id_values`	Data ID values of the dataset.
`is_prerequisite`
`is_task`	Whether this node represents a quantum or task initialization rather than a dataset (always `False`).
`parent_dataset_type_name`	Name of the dataset type (never a component).

Attributes Documentation

data_id_values: tuple[int | str | None, ...]¶

Data ID values of the dataset.

Note that keys are fixed given parent_dataset_type_name, so using only the values here speeds up comparisons.

is_task: ClassVar[Literal[False]] = False¶: Whether this node represents a quantum or task initialization rather than a dataset (always False).

parent_dataset_type_name: str¶: Name of the dataset type (never a component).
