How to Check if an App/Component Exists in uKnowva

{jcomments on}From uKnowva 2.5.1, you can do it this way:

if(JComponentHelper::exists('com_hrm')){
//component is installed and enabled....
}

For earlier versions, you can use this:

if(JComponentHelper::isEnabled('com_hrm',true)){
//component is installed and enabled....
}
