public DurationDV()
Method Detail

getActualValue

public java.lang.Object getActualValue(java.lang.String content,
                                       ValidationContext context)
                                throws InvalidDatatypeValueException
Overrides:
getActualValue in class TypeValidator

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 AbstractDateTimeDV
Parameters:
str - The lexical representation of duration object PnYn MnDTnH nMnS
date - uninitialized date object
Returns:
normalized date representation
Throws:
SchemaDateTimeException - 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 AbstractDateTimeDV
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:
INDETERMINATE if the order relationship between date1 and date2 is indeterminate. EQUAL if the order relation between date1 and date2 is EQUAL. If the strict parameter is true, return LESS_THAN if date1 is less than date2 and return GREATER_THAN if date1 is greater than date2. If the strict parameter is false, return LESS_THAN if date1 is less than OR equal to date2 and return GREATER_THAN if date1 is greater than OR equal to date2

dateToString

protected java.lang.String dateToString(int[] date)
Overrides:
dateToString in class AbstractDateTimeDV
