NAME

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

VERSION

This document describes RDF::Trine::Pattern version 0.140

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).
