Constructor Detail

DurationFormatUtils

public DurationFormatUtils()

DurationFormatUtils instances should NOT be constructed in standard programming.

This constructor is public to permit tools that require a JavaBean instance to operate.

Method Detail

formatDurationHMS

public static java.lang.String formatDurationHMS(long durationMillis)

Get the time gap as a string.

The format used is ISO8601-like: H:m:s.S.

Parameters:
durationMillis - the duration to format
Returns:
the time as a String

formatDurationISO

public static java.lang.String formatDurationISO(long durationMillis)

Get the time gap as a string.

The format used is the ISO8601 period format.

This method formats durations using the days and lower fields of the ISO format pattern, such as P7D6H5M4.321S.

Parameters:
durationMillis - the duration to format
Returns:
the time as a String

formatDuration

public static java.lang.String formatDuration(long durationMillis,
                                              java.lang.String format)

Get the time gap as a string, using the specified format, and padding with zeros and using the default timezone.

This method formats durations using the days and lower fields of the format pattern. Months and larger are not used.

Parameters:
durationMillis - the duration to format
format - the way in which to format the duration
Returns:
the time as a String

formatDuration

public static java.lang.String formatDuration(long durationMillis,
                                              java.lang.String format,
                                              boolean padWithZeros)

Get the time gap as a string, using the specified format. Padding the left hand side of numbers with zeroes is optional and the timezone may be specified.

This method formats durations using the days and lower fields of the format pattern. Months and larger are not used.

Parameters:
durationMillis - the duration to format
format - the way in which to format the duration
padWithZeros - whether to pad the left hand side of numbers with 0's
Returns:
the time as a String

formatDurationWords

public static java.lang.String formatDurationWords(long durationMillis,
                                                   boolean suppressLeadingZeroElements,
                                                   boolean suppressTrailingZeroElements)

This method formats durations using the days and lower fields of the format pattern. Months and larger are not used.

Parameters:
durationMillis - the elapsed time to report in milliseconds
suppressLeadingZeroElements - suppresses leading 0 elements
suppressTrailingZeroElements - suppresses trailing 0 elements
Returns:
the formatted text in days/hours/minutes/seconds
