Method Detail

loadInstance

public static OutputMapper loadInstance(ADag dag,
                        PegasusBag bag)
                                 throws OutputMapperFactoryException

Loads the implementing class corresponding to the value specified in the properties. If the package name is not specified with the class, then class is assumed to be in the DEFAULT_PACKAGE. The properties object passed should not be null.

In addition it ends up loading the appropriate Transfer Implementation that is required by the mapper.

Parameters:

dag - the workflow that is being refined.

bag - the bag of initialization objects

Returns:

the instance of the class implementing this interface.

Throws:

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

loadInstance

public static OutputMapper loadInstance(String className,
                        PegasusBag bag,
                        ADag dag)
                                 throws OutputMapperFactoryException

Loads the implementing class corresponding to the class. If the package name is not specified with the class, then class is assumed to be in the DEFAULT_PACKAGE. The properties object passed should not be null. In addition it ends up loading the appropriate Transfer Implementation that is required by the mapper.

Parameters:

className - the name of the class that implements the mode.It can or cannot be with the package name.

bag - the bag of initialization objects

dag - the workflow that is being refined.

Returns:

the instance of the class implementing this interface.

Throws:

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