.SH NAME
RDF::Trine::Model::StatementFilter \- Model for filtering statements based on a user\-specified criteria
.SH VERSION
.IX Header "VERSION"
This document describes RDF::Trine::Model::StatementFilter version 1.019
.SH METHODS
.IX Header "METHODS"
Beyond the methods documented below, this class inherits methods from the
RDF::Trine::Model class.
.ie n .IP """new ( $store )""" 4
.el .IP "\f(CWnew ( $store )\fR" 4
.IX Item "new ( $store )"
Returns a new statement-filter model.
.ie n .IP """count_statements ($subject, $predicate, $object)""" 4
.el .IP "\f(CWcount_statements ($subject, $predicate, $object)\fR" 4
.IX Item "count_statements ($subject, $predicate, $object)"
Returns a count of all the statements matching the specified subject,
predicate and objects. Any of the arguments may be undef to match any value.
.ie n .IP """get_statements ($subject, $predicate, $object [, $context] )""" 4
.el .IP "\f(CWget_statements ($subject, $predicate, $object [, $context] )\fR" 4
.IX Item "get_statements ($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.
.ie n .IP """get_pattern ( $bgp [, $context] )""" 4
.el .IP "\f(CWget_pattern ( $bgp [, $context] )\fR" 4
.IX Item "get_pattern ( $bgp [, $context] )"
Returns a stream object of all bindings matching the specified graph pattern.
.ie n .IP """apply_rules ( $statement )""" 4
.el .IP "\f(CWapply_rules ( $statement )\fR" 4
.IX Item "apply_rules ( $statement )"
.PD 0
.ie n .IP """rules""" 4
.el .IP \f(CWrules\fR 4
.IX Item "rules"
.PD
Returns a list of all rules in the inferencing model.
.ie n .IP """add_rule ( \e&rule )""" 4
.el .IP "\f(CWadd_rule ( \e&rule )\fR" 4
.IX Item "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.
