RDF::Query::Algebra::Minus - Algebra class for Minus patterns
VERSION
This document describes RDF::Query::Algebra::Minus version 2.908.
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.

hello,
I use AIX with ISM PILOT, I want to match something with a varible like this :
$variable = 10 #this variable is the number of the job
"$variable STARTED" # the pattern
how can use this variable to match it with the word STARTED
