NAME¶
RDF::Redland - Redland RDF Class
SYNOPSIS¶
use RDF::Redland;
my $storage=new RDF::Redland::Storage("hashes", "test", "new='yes',hash-type='memory'");
my $model=new RDF::Redland::Model($storage, "");
...
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
