QuantumKey

class lsst.pipe.base.quantum_graph_skeleton.QuantumKey(task_label: str, data_id_values: tuple[int | str | None, ...])

Bases: object

Identifier type for quantum keys in a QuantumGraphSkeleton.

Attributes Summary

data_id_values	Data ID values of the quantum.
is_task	Whether this node represents a quantum or task initialization rather than a dataset (always True).
task_label	Label of the task in the pipeline.

Attributes Documentation

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

Data ID values of the quantum.

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

is_task: ClassVar[Literal[True]] = True

Whether this node represents a quantum or task initialization rather than a dataset (always True).

task_label: str

Label of the task in the pipeline.
