Examples of WhoHasPersistence

com.flaptor.hounder.classifier.util.WhoHasPersistence
In previous versions, we added the data to a Map(token->TokenCounter) in memory. However such aproach consumes too much RAM and was discarded. In this version we add the data to a file that is lately transformed into a Map backed by a file. This class implements a file where partial data is saved, for late sort and add to the map @author rafa @see BayesCalculator#computeProbabilities() @see BayesCalculator#addData(java.util.Map,boolean,String)
