reportFoundDrivers

public static void reportFoundDrivers()

registerListener

public static void registerListener(DriverStateListener listener,
                                    Iterable<? extends PrologEngineDriver> drivers)

findDrivers

public static Set<PrologEngineDriver> findDrivers(Collection<ClassLoader> classLoaders,
                                                  Collection<URL> urls)

findDriverClasses

public static Set<Class<? extends PrologEngineDriver>> findDriverClasses(Collection<ClassLoader> classLoaders,
                                                                         Collection<URL> urls)

Answers a set with all the Prolog drivers found in the given urls. If the urls are empty will answer the drivers in the class loader classpath

Parameters:

urls -

Returns:

groupByPrologEngineName

public static <T extends PrologEngineDriver> Map<String,com.google.common.collect.Multimap<String,T>> groupByPrologEngineName(Iterable<T> drivers)

Returns a map where its key are Prolog engine names. Each entry in this map is a multimap mapping bridge library names to prolog drivers. In this way, a bridge library could be mapped to more than one Prolog driver.

Parameters:

configurations -

Returns:

groupByLibraryName

public static <T extends PrologEngineDriver> Map<String,com.google.common.collect.Multimap<String,T>> groupByLibraryName(Iterable<T> drivers)

Returns a map where its key are bridge library names. Each entry in this map is a multimap mapping Prolog engine names to prolog configurations.

Parameters:

configurations -

Returns:

orderByLibraryName

public static void orderByLibraryName(List<? extends PrologEngineDriver> drivers)

Order alphabetically a list of drivers.

Parameters:

drivers -
