Field Detail

condition

private final GlobalGrouping condition

The parameters for evaluating our rating conditions.

waitfor

private final ExpressionEvaluator waitfor

The expression that must become true for a rating to proceed.

fulfill

private final List<Appointable.Constraint> fulfill

The list of constraint that must be fulfilled to rate successful.

pick

private final HistoryAware.Pick pick

The pick we should update.

Constructor Detail

RateThread

private RateThread(HistoryAware.Pick update,
                   GlobalGrouping set,
                   ExpressionEvaluator canrate,
                   List<Appointable.Constraint> rate)

Constructs, but does not start the rating thread. The link to the target is provided via the containing instance. None of the arguments might be null.

Method Detail

run

public void run()

Runs the rate thread. If the pick is already false, we end immediately, otherwise we wait for the condition to become true. Then, we go through the list of all constraints and render the current pick a success or a failure. The last action before exiting is adding the pick to the database, if desired.

Specified by:

run in interface Runnable

Overrides:

run in class Thread

exitAction

private void exitAction(TargetDefinition target,
                        HistoryAware.Pick pick)

Always called at the end of the thread's lifetime. If database-entry is desired, we add the probably updated pick now.
