NAME

       RDF::Trine::Statement - Class for triples and triple patterns

VERSION

       This document describes RDF::Trine::Statement version 1.019

METHODS

       "new ( $s, $p, $o )"
           Returns a new Triple structure.

       "construct_args"
           Returns a list of arguments that, passed to this class' constructor, will produce a
           clone of this algebra pattern.

       "nodes"
           Returns the subject, predicate and object of the triple pattern.

       "node_names"
           Returns the method names for accessing the nodes of this statement.

       "subject"
           Returns the subject node of the triple pattern.

       "predicate"
           Returns the predicate node of the triple pattern.

       "object"
           Returns the object node of the triple pattern.

       "as_string"
           Returns the statement in a string form.

       "has_blanks"
           Returns true if any of the nodes in this statement are blank nodes.

       "sse"
           Returns the SSE string for this algebra expression.

       "from_sse ( $string, $context )"
           Parses the supplied SSE-encoded string and returns a RDF::Trine::Statement object.

       "type"
           Returns the type of this algebra expression.

       "referenced_variables"
           Returns a list of the variable names used in this algebra expression.

       "definite_variables"
           Returns a list of the variable names that will be bound after evaluating this algebra
           expression.

       "clone"
       "bind_variables ( \%bound )"
           Returns a new algebra pattern with variables named in %bound replaced by their
           corresponding bound values.

       "subsumes ( $statement )"
           Returns true if this statement will subsume the $statement when matched against a
           triple store.

       "from_redland ( $statement )"
           Given a RDF::Redland::Statement object, returns a perl-native RDF::Trine::Statement
           object.

       "rdf_compatible"
           Returns true if and only if the statement can be expressed in RDF. That is, the
           subject of the statement must be a resource or blank node; the predicate must be a
           resource; and the object must be a resource, blank node or literal.

           RDF::Trine::Statement does allow statements to be created which cannot be expressed in
           RDF - for instance, statements including variables.
