Hi Sam,

In brief -super() method is usually used to override system method of base object.

For example - validateWrite() method on table. Pseudo code -

…
boolean ret;
;

ret = super();
//Some condition below
if (<condition 1> == <condition 2>)
ret = true;
else
ret = false;

return ret;

In above method, first line (ret = super()) will call standard system validation. Subsequently that is overridden by calling some validation.

Hope this gives you an idea.

Regards,
