All Implemented Interfaces:

Serializable, Cloneable, EndpointDefining, Meriting, PropertySupplying

public class OneObservationMerit
extends AbstractMerit
implements EndpointDefining

A class defining a one-observation merit. The merit it returns is always equal to the impact factor, as long as the number of successful observations is not equal to KEY_MAXOBSERVATIONS.

Constructor Detail

OneObservationMerit

public OneObservationMerit(Map<String,String> prop)

Constructs a one-observation merit, defaulting the KEY_IMPACT and the KEY_MAXOBSERVATIONS parameters. Proper creation should be done using the AbstractMerit.createMerit(java.util.Map<java.lang.String, java.lang.String>) method. This create method also takes care of proper parameter overloading.

Method Detail

getMerit

public double getMerit(GlobalGrouping set,
                       Appointable target,
                       Collection<Appointable> ignore,
                       long dummy)

Calculates the actual time slot merit. If the number of successful observations is below KEY_MAXOBSERVATIONS, the KEY_IMPACT merit is returned. If the target definition is not history aware, one is returned.
As this merit focusses inly on number of picks, the time span is ignored.

Specified by:

getMerit in interface Meriting

Parameters:

set - Current observing conditions.

target - The actual target.

ignore - All targets, observable or not.

dummy - The relevant time span in ms.

isCompleted

public boolean isCompleted(GlobalGrouping set,
                           Appointable target)

Returns true, if the number of successful observations has reached the requested value.

Specified by:

isCompleted in interface EndpointDefining
