Class Method Details

.from_shexj(operator, **options) ⇒ Operator

Creates an operator instance from a parsed ShExJ representation

Examples:

Simple TripleConstraint

rep = JSON.parse(%({
        "type": "TripleConstraint",
        "predicate": "http://www.w3.org/1999/02/22-rdf-syntax-ns#type"
      }
))
TripleConstraint.from(rep) #=> (tripleConstraint a)

Parameters:

  • operator (Hash)
  • options (Hash) —

    ({})

Options Hash (**options):

Returns:

Raises:

  • (ArgumentError)
