Specified by:

isPrintDataAvailable in interface DateTimePrinter

Parameters:

calendrical - the calendrical to check, not null

Returns:

true if the calendrical can be printed, false if not

parse

parseText - the input text to parse, not null

position - the position to start parsing at, from 0 to the text length

Returns:

the new parse position, where negative means an error with the error position encoded using the complement ~ operator

                            int arrayIndex,
                            java.lang.String parseText,
                            boolean required)

Parse a two digit zero-prefixed number.

Parameters:
