Method Detail

defaultParameterizationOfComponent

public static ComponentInstance defaultParameterizationOfComponent(Component component)

This procedure returns a ComponentInstance of the given Component with default parameterization. Note that required interfaces are not resolved.

Parameters:

component - The component for which a random parameterization is to be returned.

Returns:

An instantiation of the component with default parameterization.

randomParameterizationOfComponent

public static ComponentInstance randomParameterizationOfComponent(Component component,
                                                                  java.util.Random rand)

This procedure returns a valid random parameterization of a given component. Random decisions are made with the help of the given Random object. Note that required interfaces are not resolved.

Parameters:

component - The component for which a random parameterization is to be returned.

rand - The Random instance for making the random decisions.

Returns:

An instantiation of the component with valid random parameterization.

getComponentsProvidingInterface

public static java.util.Collection<Component> getComponentsProvidingInterface(java.util.Collection<Component> components,
                                                                              java.lang.String providedInterface)

Searches and returns all components within a collection of components that provide a specific interface.

Parameters:

components - The collection of components to search in.

providedInterface - The interface of interest.

Returns:

A sub-collection of components all of which provide the requested providedInterface.

getAllAlgorithmSelectionInstances

public static java.util.Collection<ComponentInstance> getAllAlgorithmSelectionInstances(Component rootComponent,
                                                                                        java.util.Collection<Component> components)

Enumerates all possible component instances for a specific root component and a collection of components for resolving required interfaces. Hyperparameters are set to the default value.

Parameters:

rootComponent - The component to be considered the root.

components - The collection fo components that is used for resolving required interfaces recursively.

Returns:

A collection of component instances of the given root component with all possible algorithm choices.

getNumberOfUnparametrizedCompositions

public static int getNumberOfUnparametrizedCompositions(java.util.Collection<Component> components,
                                                        java.lang.String requiredInterface)
