Méthode Description
GenericDataModel ( FastByIDMap userData ) : System

Creates a new GenericDataModel from the given users (and their preferences). This IDataModel retains all this information in memory and is effectively immutable.

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 dataModel ) : System

Creates a new GenericDataModel containing an immutable copy of the data from another given IDataModel.

Method Details

GenericDataModel() public méthode

Creates a new GenericDataModel from the given users (and their preferences). This IDataModel retains all this information in memory and is effectively immutable.
public GenericDataModel ( FastByIDMap userData ) : System
userData FastByIDMap userData users to include; (see also )
Résultat System

GenericDataModel() public méthode

Creates a new GenericDataModel from the given users (and their preferences). This IDataModel retains all this information in memory and is effectively immutable.
public GenericDataModel ( FastByIDMap userData, FastByIDMap timestamps ) : System
userData FastByIDMap users to include; (see also )
timestamps FastByIDMap timestamps optionally, provided timestamps of preferences as milliseconds since the epoch. User IDs are mapped to maps of item IDs to long timestamps.
