NAME

       RDF::Query::Algebra::Project - Algebra class for projection

VERSION

       This document describes RDF::Query::Algebra::Project version 2.908.

METHODS

       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.

       "construct_args"
           Returns a list of arguments that, passed to this class' constructor, will produce a
           clone of this algebra pattern.

       "pattern"
           Returns the pattern to be sorted.

       "vars"
           Returns the vars to be projected to.

       "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).

       "as_spin ( $model )"
           Adds statements to the given model to represent this algebra object in the SPARQL
           Inferencing Notation (<http://www.spinrdf.org/>).

       "type"
           Returns the type of this algebra expression.

       "referenced_variables"
           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.

       "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.

       "is_solution_modifier"
           Returns true if this node is a solution modifier.
