HTTP::OAI::Error.3pm

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''.
