SparqlOptimiserQueryOptimiser Property

public static IQueryOptimiser QueryOptimiser { get; set; }

Public Shared Property QueryOptimiser As IQueryOptimiser
	Get
	Set

Property Value

Note: May be overridden by the Optimiser setting on a SparqlQueryParser.

Unlike previous releases a Query may be reoptimised using a different optimiser if desired by calling the Optimise() method again and providing a different Optimiser. This may not always fully reoptimise the query since the first optimisation will have caused any Filters and Assignments to be placed in the Triple Pattern.

Warning: Setting this to null has no effect, to disable automatic optimisation use the global property Options.QueryOptimisation. Even with this option disabled a Query can still be optimised manually by calling its Optimise() method.
