NAME
RDF::Query::Algebra::TimeGraph - Algebra class for temporal patterns
VERSION
This document describes RDF::Query::Algebra::TimeGraph version 2.911.
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.
