Interface DistributionFactory

All Known Implementing Classes:
  DistributionFactory.DefaultDistributionFactory, OrderNDistributionFactory

    public interface DistributionFactory

A thing that can make Distributions.

This decouples programs from needing to know what implementation of Distribution to instantiate for a given alphabet. It also lets you parameterise model creation for things like profile HMMs.
