Method Detail

print

void print(ChronoDisplay context,
         Appendable buffer,
         AttributeQuery attributes)
           throws IOException,
                  ChronoException

Converts the element value in given context to a formatted text.

Implementation note: The concrete element value is obtainable by the expression context.get(this).

Parameters:

context - time context with the value of this element

buffer - format buffer any text output will be sent to

attributes - query for control attributes

Throws:

IOException - if writing to buffer fails

ChronoException - if there is no suitable element rule for evaluating the value

parse

V parse(CharSequence text,
      ParsePosition status,
      AttributeQuery attributes)

Interpretes the given text as element value.

Implementation note: Any implementation will start first at the position status.getIndex() and either set the new position after successful parsing or return null in case of error.

Parameters:

text - text to be parsed

status - current parsing position

attributes - query for control attributes

Returns:

parsed element value or null if parsing was not successful
