Creating classes based on adapter pattern
Another important design pattern is the adapter design. As the name suggests, the adapter design is used for conversion of one object into another object belonging to a different class. An
adapter class will have a method that takes as input the object reference that is to be converted and outputs it into the other object reference format.
We have referred to the
cl_salv_tree_adapter standard class while making of this recipe.
In order to demonstrate the adapter, we need two classes (
input class and
output class). The
input class will be the
fac_meth_class created earlier. For the output, we will create another class
fac_meth_class2. This will serve as the class, into the format of which the ...
