Instance Method Details

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

Specifies the condition that each value node conforms to all provided shapes. This is comparable to conjunction and the logical “and” operator.

Examples:

ex:SuperShape
  a sh:NodeShape ;
  sh:property [
    sh:path ex:property ;
    sh:minCount 1 ;
  ] .

ex:ExampleAndShape
  a sh:NodeShape ;
  sh:targetNode ex:ValidInstance, ex:InvalidInstance ;
  sh:and (
    ex:SuperShape
    [
      sh:path ex:property ;
      sh:maxCount 1 ;
    ]
  ) .

Parameters:

  • node (RDF::Term)
  • options (Hash{Symbol => Object})

Returns:
