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 sh:qualifiedMaxCount or, one value for each, at the same subject.

Parameters:
