/*! \qmltype IntentServerHandler
    \inqmlmodule QtApplicationManager.SystemUI
    \inherits IntentHandler
    \ingroup system-ui-instantiable
    \brief A handler for intent requests received within the System UI.

    If intents need to be handled from within the System UI, you need to have a corresponding
    IntentServerHandler instance that is actually able to handle incoming requests. This class gives
    you the flexibility to handle multiple, different intent ids via a single IntentServerHandler
    instance or have a dedicated IntentServerHandler instance for every intent id (or any
    combination of those).

    \note For handling intent requests within an application, you have to use the application side
          component IntentHandler, which works the same way, but provides all the necessary
          meta-data in the application's info.yaml manifest file.

    For more information see IntentHandler and the description of the \l{manifest-intent}
    {meta-data in the manifest documentation}.

    Callbacks connected to the onRequestReceived signal have access to the sender's application ID.
    Due to security restrictions, this is \b not the case for such handlers implemented in an
    application context via IntentHandler.
