QuantumKey¶
- class lsst.pipe.base.quantum_graph_skeleton.QuantumKey(task_label: str, data_id_values: tuple[DataIdValue, ...], is_task: ClassVar[Literal[True]] = True)¶
Bases:
NamedTuple
Identifier type for quantum keys in a
QuantumGraphSkeleton
.Attributes Summary
Data ID values of the quantum.
Whether this node represents a quantum or task initialization rather than a dataset (always
True
).Label of the task in the pipeline.
Methods Summary
count
(value, /)Return number of occurrences of value.
index
(value[, start, stop])Return first index of value.
Attributes Documentation
- data_id_values: tuple[DataIdValue, ...]¶
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]]¶
Whether this node represents a quantum or task initialization rather than a dataset (always
True
).
Methods Documentation
- count(value, /)¶
Return number of occurrences of value.
- index(value, start=0, stop=sys.maxsize, /)¶
Return first index of value.
Raises ValueError if the value is not present.
