Method Summary

protected short
compareDates(int[] date1, int[] date2)
Overwrite compare algorithm to optimize month comparison REVISIT: this one is lack of the third parameter: boolean strict, so it doesn't override the method in the base.
protected String
dateToString(int[] date)
Converts month object representation to String
Object
getActualValue(String content, ValidationContext context)
Convert a string to a compiled form
protected int[]
parse(String str)
Parses, validates and computes normalized version of gMonth object

Method Details

compareDates

protected short compareDates(int[] date1,
                             int[] date2)
Overwrite compare algorithm to optimize month comparison REVISIT: this one is lack of the third parameter: boolean strict, so it doesn't override the method in the base. But maybe this method is not correctly implemented, and I did encounter errors when trying to add the extra parameter. I'm leaving it as is. -SG

Parameters:
date1 -
date2 -

Returns:
less, greater, equal, indeterminate

dateToString

protected String dateToString(int[] date)
Converts month object representation to String
Overrides:
dateToString in interface AbstractDateTimeDV

Parameters:
date - month object

Returns:
lexical representation of month: --MM with an optional time zone sign

getActualValue

public Object getActualValue(String content,
                             ValidationContext context)
            throws InvalidDatatypeValueException
Convert a string to a compiled form
Overrides:
getActualValue in interface TypeValidator

Parameters:
content - The lexical representation of gMonth

Returns:
a valid and normalized gMonth object

parse

protected int[] parse(String str)
            throws SchemaDateTimeException
Parses, validates and computes normalized version of gMonth object

Parameters:
str - The lexical representation of gMonth object --MM with possible time zone Z or (-),(+)hh:mm

Returns:
normalized date representation

Throws:
SchemaDateTimeException - Invalid lexical representation
