Unit

Time unit

Time units are referenced by calendar values.

classDiagram
    class TimeUnit {
        name: string
        min: number
        max: number
        duration: number
        validate(value)
    }
    class EDTFValidator {
        name: string
        validate(value)
    }
    TimeUnit --> TimeUnit: subUnit
    TimeUnit --> EDTFValidator: validator

A time unit is Iterable, which means you can get all its possible values:

  // Will output 0 to 9999 
for (let year of level0YearUnit) {
  const isLeap = GregorianCalendar.isLeap(year)
  console.log(year, isLeap)
}

Validators

There is a validator implementation that checks that a value is inside an allowed range of values:

classDiagram
    class EDTFValidator {
    }
    class MinMaxValidator {
        min: number
        max: number
    }
    EDTFValidator <|-- MinMaxValidator
