RDF::Query::Algebra::Sequence - Algebra class for a sequence of algebra operations
This document describes RDF::Query::Algebra::Sequence version 2.911.
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
new ( @patterns )
Returns a new Sequence structure.
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
Returns a list of patterns belonging to this sequence.
Returns the SSE string for this algebra expression.
Returns the SPARQL string for this algebra expression.
Returns the query as a nested set of plain data structures (no objects).
Returns the type of this algebra expression.
Returns a list of the variable names used in this algebra expression.
Returns a list of the variable names used in this algebra expression that will bind values during execution.
Returns a list of the variable names that will be bound after evaluating this algebra expression.
bind_variables ( \%bound )
Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.
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.
