getPreferredValidationApproach

public org.eclipse.rdf4j.sail.shacl.ast.ValidationApproach getPreferredValidationApproach(ConnectionsGroup connectionsGroup)

Description copied from interface: ConstraintComponent

A constraint component should decide which validation approach is going to be the optimal performance wise based on the state of the transaction and base sail.

Specified by:

getPreferredValidationApproach in interface ConstraintComponent

getOptimalBulkValidationApproach

public org.eclipse.rdf4j.sail.shacl.ast.ValidationApproach getOptimalBulkValidationApproach()

Description copied from interface: ConstraintComponent

Should return the fastest validation approach for bulk validation. When aggregating multiple constraint components the most compatible should be chosen.

Specified by:

getOptimalBulkValidationApproach in interface ConstraintComponent

requiresEvaluation

public boolean requiresEvaluation(ConnectionsGroup connectionsGroup,
 ConstraintComponent.Scope scope,
 Resource[] dataGraph,
 org.eclipse.rdf4j.sail.shacl.ast.StatementMatcher.StableRandomVariableProvider stableRandomVariableProvider)

Specified by:

requiresEvaluation in interface ConstraintComponent

Returns:

true if the constraint component should be evaluated, eg. if validation is needed.
