### DurationDatatypeValidator

    public DurationDatatypeValidator(DatatypeValidator base,
                                     java.util.Hashtable facets,
                                     boolean derivedByList)

Method Detail

### parse

    protected int[] parse(java.lang.String str,
                          int[] date)
                   throws SchemaDateTimeException

  Parses, validates and computes normalized version of duration object
  Overrides:
    parse in class DateTimeValidator
  Parameters:
    `str` - The lexical representation of duration object PnYn MnDTnH nMnS
    `date` - uninitialized date object
  Returns:
    normalized date representation
  Throws:
    java.lang.Exception - Invalid lexical representation

### compareDates

    protected short compareDates(int[] date1,
                                 int[] date2,
                                 boolean strict)

  Compares 2 given durations. (refer to W3C Schema Datatypes "3.2.6 duration")
  Overrides:
    compareDates in class DateTimeValidator
  Parameters:
    `date1` - Unnormalized duration
    `date2` - Unnormalized duration
    `strict` - (min/max)Exclusive strict == true ( LESS_THAN ) or ( GREATER_THAN ) (min/max)Inclusive strict == false (LESS_EQUAL) or (GREATER_EQUAL)
  Returns:

### dateToString

    protected java.lang.String dateToString(int[] date)

  Overrides:
    dateToString in class DateTimeValidator
