NAME
RDF::KV::Patch - Representation of RDF statements to be added or removed
SYNOPSIS
my $patch = RDF::KV::Patch->new;
$patch->add_this($s, $p, $o, $g);
$patch->remove_this($s, $p, undef, $g); # a wildcard
$patch->apply($model); # an RDF::Trine::Model instanceDESCRIPTION
This module is designed to represent a diff for RDF graphs. You add statements to its add or remove sides, then you "apply" them to a RDF::Trine::Model object. This should probably be part of RDF::Trine if there isn't something like this in there already.
METHODS
new
Stub constructor, nothing of interest.
add_this { $S, $P, $O | $statement } [, $graph ]
Add a statement, or set of terms, to the add side of the patch.
dont_add_this { $S, $P, $O | $statement } [, $graph ]
Remove a statement, or set of terms, from the add side of the patch.
remove_this { $S, $P, $O | $statement } [, $graph ]
Add a statement, or set of terms, to the remove side of the patch.
dont_remove_this { $S, $P, $O | $statement } [, $graph ]
Remove a statement, or set of terms, from the remove side of the patch.
apply $model
Apply the patch to an RDF::Trine::Model object. Statements are removed first, then added. Transactions (i.e. "begin_bulk_ops" in RDF::Trine::Model) are your responsibility.
