NAME

       HTTP::OAI::Error - Encapsulates OAI error codes

METHODS

       $err = new HTTP::OAI::Error(code=>'badArgument',[message=>'An incorrect argument was
       supplied'])
           This constructor method returns a new HTTP::OAI::Error object.

           If no message is specified, and the code is a valid OAI error code, the appropriate
           message from the OAI protocol document is the default message.

       $code = $err->code([$code])
           Returns and optionally sets the error name.

       $msg = $err->message([$msg])
           Returns and optionally sets the error message.

NOTE - noRecordsMatch

       noRecordsMatch, without additional errors, is not treated as an error code. If
       noRecordsMatch was returned by a repository the HTTP::OAI::Response object will have a
       verb 'error' and will contain the noRecordsMatch error, however is_success will return
       true.

       e.g.

               my $r = $ha->ListIdentifiers(metadataPrefix='oai_dc',from=>'3000-02-02');

               if( $r->is_success ) {
                       print "Successful\n";
               } else {
                       print "Failed\n";
               }

               print $r->verb, "\n";

       Will print "Successful" followed by "error".
