RDF::Query::Algebra::Sequence(3)
Algebra class for a sequence of algebra operations
VERSION
This document describes RDF::Query::Algebra::Sequence version 2.916.
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 blanklabel reuse
across BGPs, otherwise throws a RDF::Query::Error::QueryPatternError exception.
