nit: update macro name to reflect class name

[kaanb, 2013/05/14 23:37:09]

Done.

nit: 'for the client side of the' or 'on the client side' or so

[kaanb, 2013/05/14 23:37:09]

Done.

nit: |gl| seems to be obsolete

Done.

nit: comment is obsolete since these methods are not virtual anymore

[kaanb, 2013/05/14 23:37:09]

Done.

[no sievers, 2013/05/14 21:10:03]

make non-virtual and remove 'override'

Done.
