class QuantumGraphExecutor(ABC): 

"""Class which abstracts QuantumGraph execution. 

 

Any specific execution model is implemented in sub-class by overriding 

the `execute` method. 

""" 

 

@abstractmethod 

def execute(self, graph, butler, taskFactory): 

"""Execute whole graph. 

 

Implementation of this method depends on particular execution model 

and it has to be provided by a subclass. Execution model determines 

what happens here; it can be either actual running of the task or, 

for example, generation of the scripts for delayed batch execution. 

 

Parameters 

---------- 

graph : `~lsst.pip.base.QuantumGraph` 

Execution graph. 

butler : `~lsst.daf.butler.Butler` 

Data butler instance 

taskFactory : `~lsst.pipe.base.TaskFactory` 

Task factory.
