Xcart delivery method
 

Good day. The next question is, there is a class with ready-made module logic, at some point you need to call a method from another class, which is a child. I create a class object and call the method I need. As a result, I get the error that when creating a class object
(Too few arguments to function XLite\Logic\Order\Modifier\AModifier::__construct( ), 0 passed in )

The question is, how do I redefine the constructor?
Or it is possible to get around this somehow differently.
P.S. Already there is a ready-made logic of a working module. It is only necessary to supplement it with one method.
