try to create an instance but return an exception if this is not possible

def createInstanceFromName[T <: AnyRef](className: String, defaultInstances: => List[AnyRef])(using m: ClassTag[T]): Operation[T]

Try to create an instance of a given class by using whatever constructor is available and trying to instantiate the first parameter recursively if there is a parameter for that constructor.

Try to create an instance of a given class by using whatever constructor is available and trying to instantiate the first parameter recursively if there is a parameter for that constructor.

This is useful to instantiate nested classes which are referencing their outer class in their constructor

def existsClass(className: String, loader: ClassLoader): Operation[Boolean]
Returns

true if a class can be loaded

def loadClass[T <: AnyRef](className: String, loader: ClassLoader): Operation[Class[T]]
def loadClassEither[T <: AnyRef](className: String, loader: ClassLoader): Operation[Either[Throwable, Class[T]]]
