All Implemented Interfaces:

Refiner

public abstract class SingleFTPerXFERJobRefiner
extends AbstractRefiner

The refiner interface, that determines the functions that need to be implemented to add various types of transfer nodes to the workflow. The single in the name indicates that the refiner works with the implementation that handles one file transfer per transfer job.

Constructor Detail

SingleFTPerXFERJobRefiner

public SingleFTPerXFERJobRefiner(ADag dag,
                                 PegasusBag bag)

The overloaded constructor.

Parameters:

dag - the workflow to which transfer nodes need to be added.

bag - the bag of initialization objects

Method Detail

loadImplementations

public void loadImplementations(PegasusBag bag)
                         throws TransferImplementationFactoryException

Loads the appropriate implementations that is required by this refinement strategy for different types of transfer jobs. It calls to the factory method to load the appropriate Implementor. Loads the implementing class corresponding to the mode specified by the user at runtime in the properties file. The properties object passed should not be null.

Parameters:

bag - the bag of initialization objects

Throws:

TransferImplementationFactoryException - that nests any error that might occur during the instantiation.
