Method Details

shortTimeUnitString

public static String shortTimeUnitString(TimeUnit unit)

Return the short string for a TimeUnit.

Parameters:

unit - (undocumented)

Returns:

(undocumented)

normalizeDuration

public static scala.Tuple2<Object,TimeUnit> normalizeDuration(long milliseconds)

Find the best TimeUnit for converting milliseconds to a friendly string. Return the value after converting, also with its TimeUnit.

Parameters:

milliseconds - (undocumented)

Returns:

(undocumented)

convertToTimeUnit

public static double convertToTimeUnit(long milliseconds,
 TimeUnit unit)

Convert milliseconds to the specified unit. We cannot use TimeUnit.convert because it will discard the fractional part.

Parameters:

milliseconds - (undocumented)

unit - (undocumented)

Returns:

(undocumented)

createOutputOperationFailureForUI

public static String createOutputOperationFailureForUI(String failure)

failureReasonCell

public static scala.collection.Seq<scala.xml.Node> failureReasonCell(String failureReason,
 int rowspan,
 boolean includeFirstLineInExpandDetails)
