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
  }
