hi all basic info on oops

Former Member — Thu, 23 Aug 2007 11:16:49 GMT

hi all

i would like to know a few basic things in oops.

1. how can i know which class i have to use for a perticular referable variable.

2. how would i know that a perticular method is doing which event.

e.g. gr_table ->display( ) give output of the select querry. how would i know which method (i.e. name of method )i have to use for a perticular event and how to find the list of all methods.

what i believe in sap there are already some methods define that one has to use to trigger particular event , am i right???

3. i would like to know all the list of classes and methods and their functions.

so that i can use them in my program depending on event.

thanx

rocky
