importNow method
Imports the complete spool files. If an import is already running, waits for it and starts the next one: files that appeared during an import do not wait for the next notification. Returns the number of entries imported by this call (or by the import it joined).
Implementation
Future<int> importNow() {
if (_importing case final importing?) {
_isImportRequested = true;
return importing;
}
return _importing = _importLoop();
}
