ProblemMediatorCentral

public ProblemMediatorCentral(org.licas.PasswordHandler thePasswordHandler)

Create a new instance of ProblemMediatorCentral.

Parameters:

thePasswordHandler - for storing passwords.

Method Detail

resetValues

public void resetValues()

Reset to starting values

Overrides:

resetValues in class ProblemMediator

createStoreData

protected void createStoreData(TestSpec testSpec)
                        throws java.lang.Exception

Create a new set of problem datasets. Can be read from a file or retrieved from the distributed services. Single file assumes a single service with a file path content for a dataset to load. Also assumes CSV ','-style separator in the file.

Parameters:

testSpec - the model of the tests to perform.

Throws:

java.lang.Exception - any error.

readData

protected java.util.ArrayList<org.ai_heuristic.eval.metric.MetricDataset> readData(java.lang.String filePath,
                                                                                   java.lang.String separator)
                                                                            throws java.lang.Exception

Read a data file of values suitable for the entropy grid.

Parameters:

filePath - the path to a local file. Values only, separated by commas.

separator - the tokenizer character.

Returns:

the file parsed into data rows of string-based values.

Throws:

java.lang.Exception - any error.

getProblemsList

protected java.util.ArrayList<org.ai_heuristic.eval.metric.MetricDataset> getProblemsList(TestSpec testSpec)
                                                                                   throws java.lang.Exception

Retrieve or generate the problems list from data files or services.

Parameters:

testSpec - the test specification.

Returns:

the list of problems.

Throws:

java.lang.Exception - any error.

hasSolutions

public boolean hasSolutions()

Return true if any solutions are currently stored.

Returns:

true if solutionHierarc is not empty.

getSolutionHierarchy

public java.util.ArrayList<SolutionContainer> getSolutionHierarchy()

Get any higher level hierarchy of solutions that might have been generated.

Returns:

the totalValue of solutionHierarc.
