## NAME

RDF::Query::Algebra::Sequence - Algebra class for a sequence of algebra operations## VERSION

This document describes RDF::Query::Algebra::Sequence version 2.918.## METHODS

Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class. "new ( @patterns )" Returns a new Sequence structure. "construct_args" Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern. "patterns" Returns a list of patterns belonging to this sequence. "sse" Returns the SSE string for this algebra expression. "as_sparql" Returns the SPARQL string for this algebra expression. "as_hash" Returns the query as a nested set of plain data structures (no objects). "type" Returns the type of this algebra expression. "referenced_variables" Returns a list of the variable names used in this algebra expression. "potentially_bound" Returns a list of the variable names used in this algebra expression that will bind values during execution. "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. "check_duplicate_blanks" Returns true if blank nodes respect the SPARQL rule of no blank-label re-use across BGPs, otherwise throws a RDF::Query::Error::QueryPatternError exception.## AUTHOR
