Constructor Detail

SolverMediators

public SolverMediators(org.licas.PasswordHandler thePasswordHandler,
                       java.util.ArrayList<ModuleSolverFactory> theSolverModules)

Create a new instance of SolverMediators.

Parameters:

thePasswordHandler - the password handler.

theSolverModules - list of solver modules.

Method Detail

createServiceMediator

public abstract 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.

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 abstract 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.

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

Create and return the appropriate mediator for the current problem type.

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

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

Parameters:

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

heuristicType - the heuristic or problem-solving type, for example, simpleHeuristicType, HeuristicConst.TEXTGENETIC.

Returns:

the related problem specification object.

setServiceMediator

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

Set the service mediator.

Parameters:

theServiceMediator - the service mediator.

getServiceMediator

public org.licas.service.ServiceMediator getServiceMediator()

Get the currently created service mediator.

Returns:

the value of serviceMediator.
