    Interface for importing anything.  You are responsible for opening
    up UI and doing all of the work to make it happen.


#include "nsISupports.idl"

interface nsISupportsString;

[scriptable, uuid(469d7d5f-144c-4f07-9661-e49e40156348)]
interface nsIImportGeneric : nsISupports
  /* Use these to prepare for the import */
      "mailInterface" - nsIImportMail interface
      "mailLocation" - nsIFile, source location for mail

      "addressInterface" - nsIImportAddressBooks interface
      "addressLocation" - src location of address books (if needed!)
      "addressDestination" - uri of destination address book or null if
                new address books will be created.
  nsISupports GetData(in string dataId);

  void SetData(in string dataId, in nsISupports pData);

      "isInstalled" - if true then mail can be automatically located.
      "canUserSetLocation" - if true then the user can specify the location
        to look for mail.  If both are false, then there is no way
        to import mail from this format!
        TBD: How to specify whether or not a file or a directory
        should be specified?
      "autoFind" - for address books, is the address book located without
        using the file system - i.e. addressLocation is irrelevant.
      "supportsMultiple" - 1 or 1..n address books are imported by this format?

  long GetStatus(in string statusKind);

    When you are ready to import call this.  If it returns TRUE then
    you must call BeginImport and then repeatedly call GetProgress until
    it returns 100 % done or until ContinueImport returns FALSE.
    If this returns FALSE then BeginImport will begin and finish the import
    before it returns.
  boolean WantsProgress();

  /* Use these for the actual import */
    /* Begin import is expected to start a new thread UNLESS WantsProgress returned
      FALSE.  It is REQUIRED to call WantsProgress before calling BeginImport.
      If WantsProgress was false then this will return the success or
      failure of the import.  Failure can be reported even if WantsProgress
      returned TRUE.
  boolean BeginImport(in nsISupportsString successLog,
                      in nsISupportsString errorLog);
      If WantsProgress returned TRUE then this will indicate if the import should
      continue.  If this returns FALSE then no other methods should be called
      and the error log should be shown to the user.
  boolean ContinueImport();
      Returns the percentage done.  When this returns 100 then the import is done.
      (only valid if WantsProgress returned true)
  long GetProgress();
      Cancel an import in progress.  Again, this is only valid if WantsProgress
      returned true.
  void CancelImport();
