class lsst.pipe.base.QuantumIterData(quantumId, quantum, taskDef, prerequisites)¶
- Bases: - object- Helper class for iterating over quanta in a graph. - QuantumGraph.traversemethod needs to return topologically ordered Quanta together with their dependencies. This class is used as a value for iterator, it contains enumerated Quantum and its prerequisites.- Parameters: - quantumId : int
- Index of this Quantum, unique but arbitrary integer. 
- quantum : Quantum
- Quantum corresponding to a graph node. 
- taskDef : TaskDef
- Task to be run on this quantum. 
- prerequisites : iterable of int
- Possibly empty sequence of indices of prerequisites for this Quantum. Prerequisites include other nodes in a graph, they do not reflect data already in butler (there are no graph nodes for those).
