Method Detail

loadInstance

public static TransformationCatalog loadInstance()
                                          throws TransformationFactoryException

Connects the interface with the transformation catalog implementation. The choice of backend is configured through properties. This method uses default properties from the property singleton.

Returns:

handle to the Transformation Catalog.

Throws:

TransformationFactoryException - that nests any error that might occur during the instantiation

DEFAULT_PACKAGE_NAME

loadInstance

public static TransformationCatalog loadInstance(PegasusProperties properties)
                                          throws TransformationFactoryException

Connects the interface with the transformation catalog implementation. The choice of backend is configured through properties. This class is useful for non-singleton instances that may require changing properties.

Parameters:

properties - is an instance of properties to use.

Returns:

handle to the Transformation Catalog.

Throws:

TransformationFactoryException - that nests any error that might occur during the instantiation

loadInstance

public static TransformationCatalog loadInstance(PegasusProperties properties,
                                                 LogManager logger)
                                          throws TransformationFactoryException

Connects the interface with the transformation catalog implementation. The choice of backend is configured through properties. This class is useful for non-singleton instances that may require changing properties.

Parameters:

properties - is an instance of properties to use.

logger - handle to the logging.

Returns:

handle to the Transformation Catalog.

Throws:

TransformationFactoryException - that nests any error that might occur during the instantiation

loadInstance

public static TransformationCatalog loadInstance(PegasusBag bag)
                                          throws TransformationFactoryException

Connects the interface with the transformation catalog implementation. The choice of backend is configured through properties. This class is useful for non-singleton instances that may require changing properties.

Parameters:

bag - is bag of initialization objects

Returns:

handle to the Transformation Catalog.

Throws:

TransformationFactoryException - that nests any error that might occur during the instantiation
