NAME

       RDF::Trine::Pattern - Class for basic graph patterns

VERSION

       This document describes RDF::Trine::Pattern version 1.007

METHODS

       "new ( @triples )"
           Returns a new BasicGraphPattern structure.

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

       "triples"
           Returns a list of triples belonging to this BGP.

       "type"
       "sse"
           Returns the SSE string for 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 pattern with variables named in %bound replaced by their corresponding
           bound values.

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

       "sort_for_join_variables"
           Returns a new pattern object with the subpatterns of the referrant sorted so that they
           may be joined in order while avoiding cartesian products (if possible).
