getDebugLevel

public int getDebugLevel()

public void setDebugLevel(int value)

format

public StringBuffer format(Date date,
                  StringBuffer toAppendTo,
                  FieldPosition fieldPosition)

Returns a StringBuffer containing N or M to represent noon and midnight in the time axis of the chart. For other times of day, it returns a blank character.

This method may not return null although it may return an empty StringBuffer.

The values of 11, 13, 23, and 1 were added to the tests for the value of the hour field to handle the case where Daylight Savings Time begins or ends in the reporting period. In this case, the hour corresponding to the tick marks is shifted by an hour after the change.

Specified by:

format in class DateFormat

Parameters:

date - Date to be used in selecting the character

toAppendTo -

fieldPosition -

Returns:

Character N or M to indicate noon or midnight or a blank character to indicate other times.

parse

public Date parse(String source,
         ParsePosition pos)

Not used in this class.

This would normally be used to convert the character representation into a java.util.Date object. However, that is not possible given the nature of this class. A dummy method that returns null is used to satisfy the interface and superclass requirements. Actually calling this method will cause an exception to be raised.
