  • Field Details

    • acceptedFormats

      public static Map<SimpleDateFormat,Integer> acceptedFormats
      Map of formats accepted by the parser. Each format is associated to the time precision it induces (an integer according to Wikibase's data model).

  • Constructor Details

    • WbDateConstant

      public WbDateConstant(String origDatestamp)
      Constructor. Used for deserialization from JSON. The object will be constructed even if the time cannot be parsed (it will evaluate to null) in evaluate(org.openrefine.wikidata.schema.ExpressionContext).
      Parameters:
      origDatestamp - the date value as a string

    • evaluate

      public org.wikidata.wdtk.datamodel.interfaces.TimeValue evaluate(ExpressionContext ctxt) throws SkipSchemaExpressionException
      Description copied from interface: WbExpression
