NAME

       RDF::Query::Expression - Class for Expr expressions

VERSION

       This document describes RDF::Query::Expression version 2.919.

METHODS

       "new ( $op, @operands )"
           Returns a new Expr structure.

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

       "op"
           Returns the operator of the expression.

       "operands"
           Returns a list of the operands of the expression.

       "sse"
           Returns the SSE string for this algebra expression.

       "explain"
           Returns a string serialization of the expression appropriate for display on the  command  line.  This
           method is primarily used by the "explain" method of the subclasses of RDF::Query::Plan.

       "as_hash"
           Returns the expression 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.

       "nonaggregated_referenced_variables"
           Returns a list of the variable names used in this algebra expression except those used as aliases for
           aggregate operations.
