Uses of PreferenceArray in org.apache.mahout.cf.taste.eval
 

Method parameters in org.apache.mahout.cf.taste.eval with type arguments of type PreferenceArray
 DataModel DataModelBuilder.buildDataModel(FastByIDMap<PreferenceArray> trainingData)
           Builds a DataModel implementation to be used in an evaluation, given training data.
 

Uses of PreferenceArray in org.apache.mahout.cf.taste.impl.model
 

Classes in org.apache.mahout.cf.taste.impl.model that implement PreferenceArray
 class BooleanItemPreferenceArray
           Like BooleanUserPreferenceArray but stores preferences for one item (all item IDs the same) rather than one user.
 class BooleanUserPreferenceArray
           Like GenericUserPreferenceArray but stores, conceptually, BooleanPreference objects which have no associated preference value.
 class GenericItemPreferenceArray
           Like GenericUserPreferenceArray but stores preferences for one item (all item IDs the same) rather than one user.
 class GenericUserPreferenceArray
           This implementation maintains two parallel arrays, of user IDs and values.

          Exports the simple user IDs and preferences in the data model.
static FastByIDMap<PreferenceArray> GenericDataModel.toDataMap(FastByIDMap<java.util.Collection<Preference>> data, boolean byUser)
          Swaps, in-place, Lists for arrays in Map values .

Methods in org.apache.mahout.cf.taste.model that return types with arguments of type PreferenceArray
 FastByIDMap<PreferenceArray> JDBCDataModel.exportWithPrefs()
          Hmm, should this exist elsewhere? seems like most relevant for a DB implementation, which is not in memory, which might want to export to memory.
