          hirondelle.predict.main.prediction.PredictionAction

All Implemented Interfaces:

Action, FetchIdentifierOwner

public final class PredictionAction
extends ActionTemplateListAndEdit
implements FetchIdentifierOwner

List and edit Prediction objects.

This feature is a prime example of implementing data ownership constraints. Here, each Prediction is linked to a PredictionList. Each PredictionList is in turned linked to a specific user - the owner of the PredictionList, and all of the Predictions it contains.
