Array of Class handles "No implication of declaring a limit on no of handles?"

In reply to Parveez ahamed:

All class methods are defined with an implicit this handle argument. So your method b is really

function int top::b(top this, int i=0);
    $display("Class Handle %0d,Calling function B ",i);
    return(i);
  endfunction

and any call to a method is replaced with

$display(top::b(top1[2],2));

It happens that your method b does not refer to any class properties, so the this handle is never referenced. If instead you wrote you method b to display a

function int b();
    $display("Class Handle %0d,Calling function B ",a);
    return(i);
  endfunction

it would get converted to

function int top::b(top this);
    $display("Class Handle %0d,Calling function B ",this.a);
    return(i);
  endfunction

A null this handle would produce an error.
