Class PredictionAccuracy

java.lang.Object

org.transitime.db.structs.PredictionAccuracy

All Implemented Interfaces:

java.io.Serializable, org.hibernate.classic.Lifecycle

@Entity
public class PredictionAccuracy
extends java.lang.Object
implements org.hibernate.classic.Lifecycle, java.io.Serializable

A database object for persisting information on how accurate a prediction was compared to the actual measured arrival/departure time for the vehicle.

Serializable since Hibernate requires such.

Implements Lifecycle so that can have the onLoad() callback be called when reading in data so that can intern() member strings. In order to do this the String members could not be declared as final since they are updated after the constructor is called.
