Constructor Details

AlgorithmFactory

public AlgorithmFactory()

Constructs a new algorithm factory.

Method Details

getInstance

public static AlgorithmFactory getInstance()

Returns the default algorithm factory.

Returns:

the default algorithm factory

setInstance

public static void setInstance(AlgorithmFactory instance)

Sets the default algorithm factory.

Parameters:

instance - the default algorithm factory

getAlgorithm

public Algorithm getAlgorithm(String name,
 Problem problem)

Searches through all discovered AlgorithmProvider instances, returning an instance of the algorithm with the registered name. The algorithm is initialized using implementation-specific properties. This method must throw an ProviderNotFoundException if no suitable algorithm is found.

Parameters:

name - the name identifying the algorithm

problem - the problem to be solved

Returns:

an instance of the algorithm with the registered name

Throws:

ProviderNotFoundException - if no provider for the algorithm is available

getAlgorithm

public Algorithm getAlgorithm(String name,
 TypedProperties properties,
 Problem problem)

Searches through all discovered AlgorithmProvider instances, returning an instance of the algorithm with the registered name. The algorithm is initialized using implementation-specific properties. This method must throw an ProviderNotFoundException if no suitable algorithm is found.

Parameters:

name - the name identifying the algorithm

properties - the implementation-specific properties

problem - the problem to be solved

Returns:

an instance of the algorithm with the registered name

Throws:

ProviderNotFoundException - if no provider for the algorithm is available

getAllDiagnosticToolAlgorithms

public Set<String> getAllDiagnosticToolAlgorithms()

Returns the names of all algorithms that have been registered to appear in the diagnostic tool.

Returns:

all diagnostic tool algorithm names
