findClass()

ObjectState * StartupHelperPrivate::findClass ( QString  classname )

static

findClass finds a class in the list of registerd classes by name

Parameters

classname

name of the class to find

Returns

pointer to ObjectState or nullptr if not found

getClassesRecursive()

bool StartupHelperPrivate::getClassesRecursive ( QStringList  backtrace, QStringList &  globalDependencies, const ObjectState &  object  )

static

getClassesRecursive gets all classes and their dependencies starting from the passed ObjectState.

Parameters

backtrace	the list of classes which depend on the current class
globalDependencies	the ordered list of classes which should be extended
object	the class to start with

Returns

true if dependencies are fine, false if we have missing or circular dependencies

start()

bool StartupHelperPrivate::start ( )

static

Creates all Singletons and calls init() on Components in the correct order The function ensures that all dependencies marked with "dependsOn" are respected.

Returns

true if creation of all singletons, calling init() on all components and postInit() on all singletons succeeded.

stop()

bool StartupHelperPrivate::stop ( )

static

Deletes all Singleton Instances and calls deinit() on all Components The Singleton Instances and Components are called in reversed order compared to the startup.

Returns

true if calling preDestroy() on all singletons, deinit() on all components and deleting all singletons succeeded
