NAME
       Wallet::ACL::Nested - Wallet ACL verifier to check another ACL


SYNOPSIS
           my $verifier = Wallet::ACL::Nested->new;
           my $status = $verifier->check ($principal, $acl);
           if (not defined $status) {
               die "Something failed: ", $verifier->error, "\n";
           } elsif ($status) {
               print "Access granted\n";
           } else {
               print "Access denied\n";
           }


DESCRIPTION
       Wallet::ACL::Nested checks whether the principal is permitted by another named ACL and, if so, returns
       success.  It is used to nest one ACL inside another.


METHODS
       new()
           Creates a new ACL verifier.

       check(PRINCIPAL, ACL)
           Returns true if PRINCIPAL is granted access according to the nested ACL, specified by name.  Returns
           false if it is not, and undef on error.

       error([ERROR ...])
           Returns the error of the last failing operation or undef if no operations have failed.  Callers
           should call this function to get the error message after an undef return from any other instance
           method.  The returned errors will generally come from the nested child ACL.
