Method Summary
java.lang.Object AbstractCombiningEnricher(AttributeSensor target)

java.lang.Object compute()

supply the computation in terms of subscribed variables; by default this is only invoked once all fields have been set at least once, then subsequently on any change to either of them
void setEntity(EntityLocal entity)

protected void subscribe(java.lang.String varName, AttributeSensor sensor)

subscribes to a given sensor on the entity where this enricher is attached, setting the value in the variable name indicated, which must be a field in this class
protected void subscribe(java.lang.reflect.Field field, AttributeSensor sensor)

@see #subscribe(String, AttributeSensor)
protected void subscribe(java.lang.String varName, Entity source, AttributeSensor sensor)

subscribes to a given sensor on the given entity, setting the value in the variable name indicated, which must be a field in this class
protected void subscribe(java.lang.reflect.Field field, Entity source, AttributeSensor sensor)

@see #subscribe(String, AttributeSensor)
