Generic method of routing through an object tree to invoke a specific method for certain objects of said tree

摘要

The invention consists of defining a generic class and a plurality of specific classes which extend from said generic class. Said specific classes are intended to be made into instances for the generation of an object tree. The generic class comprises a generic method of invoking a specific method of a specific class for the objects of the tree which are instances of this specific class. For a current object of the tree the generic method invokes said specific method if the current object is an instance of said specific class and it is recursively executed for the variables of the current object which are instances of one of said specific classes.
