RDF::Query::Algebra::Filter - Algebra class for Filter expressions
VERSION
This document describes RDF::Query::Algebra::Filter version 2.908.
METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
"new ( $expression, $pattern )"
Returns a new Filter structure.
"construct_args"
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
"expr"
Returns the filter expression.
"pattern"
Returns the filter pattern.
"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.
"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.
