RDF::Redland - Redland RDF Class

This class initialises the Redland RDF classes.
See the main classes for full detail: the RDF::Redland::Node manpage, the RDF::Redland::BlankNode manpage, the RDF::Redland::URINode manpage, the RDF::Redland::LiteralNode manpage, the RDF::Redland::XMLLiteralNode manpage, the RDF::Redland::URI manpage, the RDF::Redland::Statement manpage, the RDF::Redland::Model manpage, the RDF::Redland::Storage manpage, the RDF::Redland::Parser manpage, the RDF::Redland::Query manpage, the RDF::Redland::QueryResults manpage, the RDF::Redland::Iterator manpage, the RDF::Redland::Stream manpage and the RDF::Redland::RSS manpage.
Set SUB as the subroutine to be called on any Redland error, warning or log message. The subroutine must have the followign signature:
sub handler ($$$$$$$$$) { my($code, $level, $facility, $message, $line, $column, $byte, $file, $uri)=@_; # int error code # int log level # int facility causing the error (parsing, serializing, ...) # string error message # int line number (<0 if not relevant) # int column number (<0 if not relevant) # int byte number (<0 if not relevant) # string file name or undef # string URI or undef # ...do something with the information ... };
RDF::Redland::set_log_handler(\&handler);
Reset redland to use the default logging handler, typically printing the message to stdout or stderr and exiting on a fatal error.
The method set_log_handler is much more flexible than this and includes this functionality.
Set SUB as the subroutine to be called on a Redland error with the error message as the single argument. For example:
RDF::Redland::set_error_handler(sub { my $msg=shift; # Do something with $msg });
The default if this is not set, is to run die $msg
The method set_log_handler is much more flexible than this and includes this functionality.
Set SUB as the subroutine to be called on a Redland warning with the warning message as the single argument. For example:
RDF::Redland::set_warning_handler(sub { my $msg=shift; # Do something with $msg });
The default if this is not set, is to run warn $msg
