DataGenerator is a Java library for systematically producing large volumes of data. DataGenerator frames data production as a modeling problem, with a user providing a model of dependencies among variables and the library traversing the model to produce relevant data sets.
Separate each of the functions in https://github.com/FINRAOS/DataGenerator/blob/master/dg-core/src/main/java/org/finra/datagenerator/consumer/EquivalenceClassTransformer.java to separate classes implementing a common interface.
