ADDING STANDARD TOOLBAR IN OOALV

                                       ADDING STANDARD TOOLBAR IN OOALV

Normally ,when we output the alv in old abap , we have multiple feature like downloading , sorting, sending into excel file and many more.To use the same functionality in OOALV we need to use some classes. CL_SALV_FUNCTIONS_LIST.
 and create a reference object for this and get 2 methods:
                                                       GET_FUNCTIONS( ).
                           
                           SET_ALL( ABAP_TRUE ).

Factory pattern is used when we have a super class with multiple sub-classes and, based on input, we need to return one of the sub-classes. This pattern removes the responsibility of instantiation of a class from the client program to the factory class.
