init

public static void init(Class<? extends ContextListener> callerClass,
                        Supplier<String> repositoryNameSupplier,
                        Supplier<List<? extends AbstractETL<?,?>>> etlSupplier,
                        List<Class<? extends ILoader<?>>> loaderClasses)

Constructs an instance of the MainContext in a dedicated thread.

Parameters:

callerClass - the class of the object that called this function

repositoryNameSupplier - a getter function for retrieving the name of the targeted repository

etlSupplier - a function that provides all AbstractETLs required for harvesting

loaderClasses - a list of ILoader classes for loading documents to a search index

Returns:

true, if the initialization phase has finished

hasFailed

public static boolean hasFailed()

Checks if the initialization of the MainContext has failed.

Returns:

true, if the initialization has failed

destroy

public static void destroy()
