How to access nested object parameters...

[szbztz]

Ok this might be very simple to few but I simply can't figure it out. If I var_dump a $this variable in a script I get the following...object(ModRokSprocket)#1098 (4) {  ["params":protected]=>  object(RokCommon_Registry)#1061 (1) {    ["data":protected]=>    object(stdClass)#1058 (31) {      ["run_content_plugins"]=>      string( "onmodule"      ["provider"]=>      string(6) "joomla"      ["layout"]=>      string( "features"      ["joomla_articles"]=>      object(stdClass)#1051 (7) {        ["1"]=>        object(stdClass)#1077 (1) {          ["root"]=>          object(stdClass)#935 (1) {            ["article"]=>            string(1) "3"          }        }        ["2"]=>        object(stdClass)#1052 (1) {          ["root"]=>          object(stdClass)#1004 (1) {            ["article"]=>            string(1) "4"          }        }

If id do say $this->params = NULL it works but how can I set the data for example because if I do $this->params->data is wrong or $this->params['RokCommon_Registry']->data is also a no go...
