RDF::Query::Algebra::Project - Algebra class for projection
This document describes RDF::Query::Algebra::Project version 2.917.
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
new ( $pattern, \@vars_and_exprs )
Returns a new Project structure.
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
Returns the pattern to be sorted.
Returns the vars to be projected to.
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).
as_spin ( $model )
Adds statements to the given model to represent this algebra object in the SPARQL Inferencing Notation (http://www.spinrdf.org/).
Returns the type of this algebra expression.
Returns a list of the variable names used in this algebra expression.
bind_variables ( \%bound )
Returns a new algebra pattern with variables named in %bound replaced by their corresponding bound values.
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.
Returns true if this node is a solution modifier.
