Constructor Detail

LinkProblemMediator

public LinkProblemMediator(org.licas.PasswordHandler thePasswordHandler)

Create a new instance of LinkProblemMediator.

Parameters:

thePasswordHandler - for storing passwords.

Method Detail

solve

public Result solve(TestSpec testSpec)
             throws java.lang.Exception

Optimise the solutions using the appropriate framework.

Parameters:

testSpec - the model of the tests to perform.

Returns:

clusters of solutions or references from the latest optimisation phase. Each service is asked for its links and this is returned as the clustering.

Throws:

java.lang.Exception - any error.

resetForNextRun

public boolean resetForNextRun(java.util.HashMap varList)
                        throws java.lang.Exception

Reset the problem-solving structures for the next run. In this case, remove the named solutions from the list of current ones.

Specified by:

resetForNextRun in class ProblemMediator

Parameters:

varList - a list of variables as key-value pairs. Should include the service type.

Returns:

true if all are removed, false otherwise.

Throws:

java.lang.Exception - any error.

toClusters

protected ClusterResult toClusters(TestSpec testSpec)
                            throws java.lang.Exception

Ask each service in turn who it is clustered with.

Parameters:

testSpec - the model of the tests to perform.

Returns:

list of clusters for the services.

Throws:

java.lang.Exception - any error.

getResultXml

public org.licas_xml.abs.Element getResultXml()
                                       throws java.lang.Exception

Get the results of the test.

Returns:

the test results in XML format.

Throws:

java.lang.Exception - any error.
