Here we define a class which creates different types of instances of cl_animal class and the advantage on this is that we can use the cl_introduce class to act on any child class of cl_animal type. The purpose is to not change the interface and use a common procedure that is going to be prepared to function on these classes.

 Finally the code ends like this: 







 




start-of-selection.
  data wa_animal type ref to cl_animal.

  wa_animal = cl_animal_factory=>create_animal( 1 ).
  cl_introducer=>introduce( wa_animal ). " The i_animal parameter is implicitly specified. Useful when is only one parameter.
  write /.

  wa_animal = cl_animal_factory=>create_animal( 2 ).
  cl_introducer=>introduce( i_animal = wa_animal ). "  The i_animal parameter is explicitly specified and is necessary its use when is more than one paramter.
  write /.

  wa_animal = cl_animal_factory=>create_animal( 3 ).
  cl_introducer=>introduce( wa_animal ).
