Suggest Edits
Attribute type idType specific restriction parameters
fractionminValue: Minimum fraction value (inclusive)
maxValue: Maximum fraction value (inclusive)
patterns: List of patters that the value must match (Java Pattern). Values has to match all the patters. Pattern is only matched against the attribute value - without unit.
units: List of possible units to use (units have to be defined in unitsOfMeasure section of datastandard)

All restrictions are validated in provided order.

Attribute validation will fail on the first unfulfilled restriction.

Accepted are fraction values (i.e. 1/2) and decimal values (i.e. 0.5).

Code Examples:

{
  "id" : "WRENCH_HEAD_SIZE_INCH",
  "name" : "Wrench Head Size (inch)",
  "type" : {
    "id" : "fraction",
    "restriction" : {
      "parameters" : {
        "minValue" : "1 / 64",
        "maxValue" : "99"
      }
    }
  }
}

Attribute fractionAttribute = AttributeBuilder
        .fractionAttribute("WRENCH_HEAD_SIZE_INCH", "Wrench Head Size (inch)")
        .withMinValue(BigFraction.getReducedFraction(1, 64))
        .withMaxValue(new BigFraction(99))
        .build();
