This document describes RDF::Trine::Model::StatementFilter version 1.019

Beyond the methods documented below, this class inherits methods from the RDF::Trine::Model class.

"new ( $store )"
Returns a new statement-filter model.
"count_statements ($subject, $predicate, $object)"

"get_statements ($subject, $predicate, $object [, $context] )"
Returns a stream object of all statements matching the specified subject, predicate and objects from all of the rdf stores. Any of the arguments may be undef to match any value.
"get_pattern ( $bgp [, $context] )"
Returns a stream object of all bindings matching the specified graph pattern.
"apply_rules ( $statement )"
"rules"
Returns a list of all rules in the inferencing model.
"add_rule ( \&rule )"
Adds a rule to the inferencing model. The rule should be a CODE reference that, when passed a statement object, will return true if the statement should be allowed in the model, false if it should be filtered out.
