Field Detail

resultsBetter

protected boolean resultsBetter

True if the current set of results are better than the previous set

Constructor Detail

IterateMediatorCentral

public IterateMediatorCentral(org.licas.PasswordHandler thePasswordHandler)

Create a new instance of IterateProblemMediator.

Parameters:

thePasswordHandler - for storing passwords.

Method Detail

resetValues

public void resetValues()

Reset to starting values

Overrides:

resetValues in class ProblemMediatorCentral

solutionsToProcess

public boolean solutionsToProcess()

Return true if this spec still has solutions to process. This default version checks that the solutions list is not empty.

Specified by:

solutionsToProcess in interface IterateMediatorDef

Returns:

true if there are still solutions that can be solved.

calcTestEnded

protected void calcTestEnded(MatchResult solutionSet)
                      throws java.lang.Exception

This method checks for conditions that indicate that the test runs have or should be terminated. This method should be called internally by any derived class of ProblemMediator. It is included here with a default evaluation that checks that there are still solutions to evaluate.

Parameters:

solutionSet - the last solution set to evaluate.

Throws:

java.lang.Exception - any error.

getResultsBetter

public boolean getResultsBetter()

Return true if the current set of results are better than the previous set of results. This is not set automatically and needs to be implemented by any derived class.

Specified by:

getResultsBetter in interface IterateMediatorDef

Returns:

the value of resultsNotBetter.
