public TransformationSelector()

Method Detail

getTCEntry

public abstract List getTCEntry(List tcentries)

Takes a list of TransformationCatalogEntry objects and returns 1 or many TransformationCatalogEntry objects as a list depending on the type of selection algorithm. The Random and RoundRobin implementation ensure that only one entry is returned and should be run last when chaining multiple selectors

Parameters:

tcentries - List

Returns:

List

loadTXSelector

public static TransformationSelector loadTXSelector(String className)
                                             throws FactoryException

Loads the implementing class corresponding to the mode specified by the user at runtime in the properties file.

Parameters:

className - String The name of the class that implements the mode. It is the name of the class, not the complete name with package. That is added by itself.

Returns:

TransformationSelector

Throws:

FactoryException - that nests any error that might occur during the instantiation of the implementation.
