Instance Method Details

#conforms(node, path:, value_nodes:, depth: 0, **options) ⇒ Array<SHACL::ValidationResult>

Specifies the condition that a specified number of value nodes conforms to the given shape. Each ‘sh:qualifiedValueShape` can have: one value for `sh:qualifiedMinCount`, one value for s`h:qualifiedMaxCount` or, one value for each, at the same subject.

Parameters:

  • value_nodes (Array<RDF::Term>)
  • options (Hash{Symbol => Object})

Returns:
