NAME
RDF::Query::Algebra::TimeGraph - Algebra class for temporal patterns
VERSION
This document describes RDF::Query::Algebra::TimeGraph version 2.918.
METHODS
Beyond the methods documented below, this class inherits methods from the RDF::Query::Algebra class.
new ( $interval, $pattern, $time_triples )-
Returns a new TimeGraph structure.
construct_args-
Returns a list of arguments that, passed to this class' constructor, will produce a clone of this algebra pattern.
interval-
Returns the time interval node of the temporal graph expression.
pattern-
Returns the graph pattern of the temporal graph expression.
time_triples-
Returns the triples describing the time interval of the temporal graph.
sse-
Returns the SSE string for this algebra expression.
as_sparql-
Returns the SPARQL string for this algebra expression.
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.
