How to get PermissionKind from BasePermissions?

Question

There is a simple function to add permissions to collection:

// Set up permissions.
BasePermissions permissions = new BasePermissions();
permissions.Set(PermissionKind.ViewListItems);
permissions.Set(PermissionKind.AddListItems);
permissions.Set(PermissionKind.EditListItems);
permissions.Set(PermissionKind.DeleteListItems);

But how to get assigned permissions back from existing BasePermissions object? I cannot find a function for that. There is only a function to check, if specific kind of permission is assigned or not. How to get the list of all assigned PermissionKind's?

Thank you.

After searching for a solution, I found nothing better than just sequentially checking all possible permissions to find right one as follows:

  PermissionKind kind = PermissionKind.EmptyMask;
  foreach (PermissionKind k in Enum.GetValues(typeof(PermissionKind)))
  {
    if (roleDefinition.BasePermissions.Has(k)) 
      kind = k;
    else break;
  }

Because integer values for enumeration consistently increase, this must stop cycle on maximum available permission. Hope somebody could find a better way.
