GenericDataModel Class

NReco.Recommender Class Library

A simple IDataModel which uses a given list of users as its data source. This implementation is mostly useful for small experiments and is not recommended for contexts where performance is important.

The GenericDataModel type exposes the following members.

Constructors

	Name	Description
	GenericDataModel(FastByIDMap<IPreferenceArray>)	Creates a new GenericDataModel from the given users (and their preferences). This IDataModel retains all this information in memory and is effectively immutable.
	GenericDataModel(IDataModel)	Creates a new GenericDataModel containing an immutable copy of the data from another given IDataModel.
	GenericDataModel(FastByIDMap<IPreferenceArray>, FastByIDMap<FastByIDMap<Nullable<DateTime>>>)	Creates a new GenericDataModel from the given users (and their preferences). This IDataModel retains all this information in memory and is effectively immutable.
