detailsRequested

public void detailsRequested()

Description copied from interface: PlanEvaluation

Tells the evaluation that the user has requested more information. For some evaluations, the work will not be done until this method is called. Until then, the value returned by PlanEvaluation.getValue() will just be a place-holder that indicates that more information is available. This method will then typically change that value to show the real result of the evalutaion.

It is recommended that any evaluations that require a substantial amount of computation be handled in that delayed, "when requested" fashion.
