I am creating a plugin for my oxwall site. It is coming good. But I have 4 type of user roles in my oxwall site.

A plugin page must be shown to each user with different content.

I have got the user role id, using the below code. 

$id = OW::getUser()->getId();  

$roleid= BOL_AuthorizationService::getInstance()->findUserRoleList($id);

$rolename=($roleid[0]->name);

$userroleId=($roleid[0]->id);

Using this $userroleId, I can able to display different content for each user role. 

But some plugins like, Groups and other plugins using,

BOL_Authorization

How to do that?
