mergeclasses.Split class
The program splits a class. All the objects that you select from thefirst class (from class) are allocated to the second class (to class)and are removed from the first class.
You can select objects in a selection function. All the objects youselect in this function are split off into the second class.
Merge classes
The program merges two classes. All the objects allocated to the firstclass (from class) are allocated to the second class (to class) andremoved from the first class.
If you want to merge several classes, you need to repeat this processfor each class.
In both cases, only objects that are not classes are reallocated.
The two classes can have different class types.
If objects in the source class have inherited characteristic values(passed down a class hierarchy), these values are deleted when youreallocate the objects.
Precondition
The classes must have the same characteristics.
If the class types are different, the objects cannot be classified inother classes of the target class type - only in the target class.
You can only reallocated objects between class types that are notvariant class types and class types where objects cannot be used morethan once.
