DESCRIPTION
This class initialises the Redland RDF classes.
See the main classes for full detail: RDF::Redland::Node,
RDF::Redland::BlankNode, RDF::Redland::URINode,
RDF::Redland::LiteralNode, RDF::Redland::XMLLiteralNode,
RDF::Redland::URI, RDF::Redland::Statement, RDF::Redland::Model,
RDF::Redland::Storage, RDF::Redland::Parser, RDF::Redland::Query,
RDF::Redland::QueryResults, RDF::Redland::Iterator,
RDF::Redland::Stream and RDF::Redland::RSS.
STATIC METHODS
set_log_handler SUB
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_log_handler
Reset redland to use the default logging handler, typically
printing the message to stdout or stderr and exiting on a fatal
error.
set_error_handler SUB
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
set_warning_handler SUB
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
