Constructor Detail

DefaultSolverMediators

public DefaultSolverMediators(org.licas.PasswordHandler thePasswordHandler,
                              java.util.ArrayList theSolverModules)

Create a new instance of DefaultSolverMediators.

Parameters:

thePasswordHandler - the password handler.

theSolverModules - list of solver modules.

Method Detail

setServiceMediator

public void setServiceMediator(org.licas.service.ServiceMediator theServiceMediator)

Set the service mediator.

Overrides:

setServiceMediator in class SolverMediators

Parameters:

theServiceMediator - the service mediator.

getServiceMediator

public org.licas.service.ServiceMediator getServiceMediator()

Get the currently created service mediator.

Overrides:

getServiceMediator in class SolverMediators

Returns:

the value of serviceMediator.

createServiceMediator

public org.licas.service.ServiceMediator createServiceMediator(java.lang.String solverType)
                                                        throws java.lang.Exception

Create and return the appropriate service mediator for the problem type. If one has already been created, return it instead, so the mediator should be created only once. This mediator creates and controls the flow of information between the services that are run. The default version is SolverMediators.

Specified by:

createServiceMediator in class SolverMediators

Parameters:

solverType - the type of test framework to solve the problem.

Returns:

the appropriate service mediator for solving the problem.

Throws:

java.lang.Exception - any error.

getTestMediator

public TestDef getTestMediator(java.lang.String solverType,
                               java.lang.String serviceType)
                        throws java.lang.Exception

Create and return the appropriate test mediator to execute the services in the framework.

Specified by:

getTestMediator in class SolverMediators

Parameters:

solverType - the type of test framework to solve the problem.

serviceType - the type of services that are created.

Returns:

the appropriate TestDef class to run and execute the script in the test loop.

Throws:

java.lang.Exception - any error.

getSolverFrameworkMediator

public Evaluator getSolverFrameworkMediator(java.lang.String solverType,
                                            java.lang.String heuristicType)

Create and return the appropriate mediator for the current problem type. This default implementation returns a GridEvaluator or a LinkEvaluator.

Specified by:

getSolverFrameworkMediator in class SolverMediators

Parameters:

solverType - the type of test framework to solve the problem.

heuristicType - the heuristic or problem-solving type.

Returns:

the appropriate evaluation mediator for solving the problem.

getProblemMediator

public ProblemMediator getProblemMediator(java.lang.String solverType,
                                          java.lang.String heuristicType)

Get the problem specification object related to the current problem type.

Specified by:

getProblemMediator in class SolverMediators

Parameters:

solverType - the type of test framework to solve the problem.

heuristicType - the heuristic or problem-solving type, for example, HeuristicConst.GENETICALGORITHM or FREQUENCY.

Returns:

the related problem specification object.
