Method Details

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 interface 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 String dateToString(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date)
Overrides:
dateToString in interface AbstractDateTimeDV

getActualValue

public Object getActualValue(String content,
                             ValidationContext context)
            throws InvalidDatatypeValueException
Overrides:
getActualValue in interface TypeValidator

getDuration

protected Duration getDuration(org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData date)
Overrides:
getDuration in interface AbstractDateTimeDV

parse

protected org.apache.xerces.impl.dv.xs.AbstractDateTimeDV.DateTimeData parse(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

parseSecond

protected double parseSecond(String buffer,
                             int start,
                             int end)
            throws NumberFormatException
Overrides:
parseSecond in interface AbstractDateTimeDV
