Method Detail

### getActualValue

    public java.lang.Object getActualValue(java.lang.String content,
                                           ValidationContext context)
                                    throws InvalidDatatypeValueException

  Specified by:
    `getActualValue` in class `TypeValidator`
  Throws:
    `InvalidDatatypeValueException`

### parse

    protected org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData parse(java.lang.String str,
                                                                                 int durationType)
                                                                          throws SchemaDateTimeException

  Parses, validates and computes normalized version of duration object

  Parameters:
    `str` - The lexical representation of duration object PnYn MnDTnH nMnS
    `durationType` -
  Returns:
    normalized date representation
  Throws:
    `SchemaDateTimeException` - Invalid lexical representation

### compareDates

    protected short compareDates(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date1,
                                 org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData 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

### parseSecond

    protected double parseSecond(java.lang.String buffer,
                                 int start,
                                 int end)
                          throws java.lang.NumberFormatException

  Overrides:
    `parseSecond` in class `AbstractDateTimeDV`
  Throws:
    `java.lang.NumberFormatException`

### dateToString

    protected java.lang.String dateToString(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date)

  Overrides:
    `dateToString` in class `AbstractDateTimeDV`

### getDuration

    protected javax.xml.datatype.Duration getDuration(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date)

  Overrides:
    `getDuration` in class `AbstractDateTimeDV`
