Detailed Description
A KTextEditor command-line Command can use extension interfaces, but it does not need to.
So as a KTextEditor implementator you have to cast the Command to the desired interface and then check, whether the cast returns NULL or the valid interface.
Use qobject_cast to cast a Command cmd into the DesiredExtensionInterface, example:
// cmd is of type KTextEditor::Command* KTextEditor::DesiredExtensionInterface *iface = qobject_cast<KTextEditor::DesiredExtensionInterface*>( cmd ); if( iface ) { // the implementation supports the interface // do stuff } else { // the implementation does not support the interface }
