NAME¶

RDF::Query::Algebra::TimeGraph - Algebra class for temporal patterns

VERSION¶

This document describes RDF::Query::Algebra::TimeGraph version 2.908.

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.
