NAME

       RDF::Query::Algebra::Minus - Algebra class for Minus patterns

VERSION

       This document describes RDF::Query::Algebra::Minus version 2.910.

METHODS

       Beyond the methods documented below, this class inherits methods from the
       RDF::Query::Algebra class.

       "new ( $pattern, $opt_pattern )"
           Returns a new Minus 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 base pattern (LHS) onto which the minus pattern matches.

       "minus"
           Returns the minus pattern (RHS).

       "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.
