  ix.iplan.ChecksimPlanEvaluation

All Implemented Interfaces:

PlanEvaluation

public class ChecksimPlanEvaluation
extends java.lang.Object
implements PlanEvaluation

A plan-evaluation that runs the plan-checking simulator. It's also an illustration of an evaluation that's just a place-holder until the user requests that the actual evaluation be produced. The value is initially "run". The simulator isn't run until the user requests the details. Then the simulator's output is displayed in a new window, and the value becomes either "ok" or "n problems", where n is the number of problems found by the simulator. If the details are requested again, the simulator's output (which was saved) is displayed again.

Method Detail

getValue

public java.lang.Object getValue()

Description copied from interface: PlanEvaluation

Returns the current value of this evaluation. Note that the value may change after the user requests more information.

PlanEvaluation.detailsRequested()

hasDetails

public boolean hasDetails()

Description copied from interface: PlanEvaluation

Indicates whether or not more information is available if the used requests it.

Specified by:

PlanEvaluation.detailsRequested()

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.
