Field Detail

• private java.lang.String currentTaskName

  Name of the current task

• private final java.lang.String id

  Identifier of this stop watch. Handy when we have output from multiple stop watches and need to distinguish between them in log or console output.

• private StopWatch.TaskInfo lastTaskInfo

• private boolean running

  Is the stop watch currently running?

• private final java.util.Deque<TaskInfo> runningTasks

• private int taskCount

• private final java.util.Deque<TaskInfo> taskList

• private long totalTimeMillis

  Total running time

Constructor Detail

• public StopWatch()

  Construct a new stop watch. Does not start any task.

• public StopWatch(java.lang.String id)

  Construct a new stop watch with the given id. Does not start any task.

  Parameters:

  id - identifier for this stop watch. Handy when we have output from multiple stop watches and need to distinguish between them.

Method Detail

• @java.lang.Override public int compare(StopWatch.TaskInfo o1, StopWatch.TaskInfo o2)

• public void complete()

• public StopWatch.TaskInfo getLastTaskInfo()

  Return the last task as a TaskInfo object.

• public java.lang.String getLastTaskName()

  Return the name of the last task.

• public long getLastTaskTimeMillis()

  Return the time taken by the last task.

• public int getTaskCount()

  Return the number of tasks timed.

• public StopWatch.TaskInfo[] getTaskInfo()

  Return an array of the data for tasks performed.

• public long getTotalTimeMillis()

  Return the total time in milliseconds for all tasks.

• public double getTotalTimeSeconds()

  Return the total time in seconds for all tasks.

• public boolean isRunning()

  Return whether the stop watch is currently running.

• public java.lang.String prettyPrint()

  Return a string with a table describing all tasks performed. For custom reporting, call getTaskInfo() and use the task info directly.

• public java.lang.String shortSummary()

  Return a short description of the total running time.

• public void start()

  Start an unnamed task. The results are undefined if stop() or timing methods are called without invoking this method.

  stop()

• public void start(java.lang.String taskName)

  Start a named task. The results are undefined if stop() or timing methods are called without invoking this method.

  Parameters:

  taskName - the name of the task to start

  See Also:

  stop()

• public void stop()

  Stop the current task. The results are undefined if timing methods are called without invoking at least one pair start() / stop() methods.

  See Also:

  start()

• @java.lang.Override public java.lang.String toString()

  Return an informative string describing all tasks performed For custom reporting, call getTaskInfo() and use the task info directly.
