Method Detail

getActualValue

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

Overrides:

getActualValue in class TypeValidator

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

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
