Each statistic entry is composed as follow: count: statistic counter error: statistic error counter minTime: minimum time for this entry (automatically computed) maxTime: maximum time for this entry (automatically computed) totalTime: total time for this entry author:    Emmanuel Cecchet author:    Julie Marguerite version:    1.0 Constructor Summary public   Stats(String statName)      Creates a new Stats instance. Method Summary public  void displayOnStdout()      Displays the statistics on the standard output. public synchronized  int getCacheHit()      public synchronized  int getCount()      Gets current count of an entry. public synchronized  int getError()      public synchronized  long getMaxTime()      public synchronized  long getMinTime()      public  String getName()      Gets the name of the current stat. public synchronized  long getTotalTime()      public synchronized  void incrementCacheHit()      Increments an entry cache hit by one. public synchronized  void incrementCount()      Increments an entry count by one. public synchronized  void incrementError()      Increments an entry error by one. public synchronized  void merge(Stats anotherStat)      Adds the entries of another Stats object to this one. public  String multipleLineDisplay()      Displays the statistics information on multiple lines. public synchronized  void reset()      Resets all entries to 0. public  String singleLineDisplay()      public  String[] toStringTable()      Get the stat information in the form of a String table. public synchronized  void updateTime(long time)      Adds a new time sample for this entry. Constructor Detail Stats public Stats(String statName)(Code) Creates a new Stats instance. The entries are reset to 0. Parameters:   statName - The stat name Method Detail displayOnStdout public void displayOnStdout()(Code) Displays the statistics on the standard output. getCacheHit public synchronized int getCacheHit()(Code) Gets current cache hit count of an entry current entry cache hit value getCount public synchronized int getCount()(Code) Gets current count of an entry. current entry count value getError public synchronized int getError()(Code) Gets current error count of an entry current entry error value getMaxTime public synchronized long getMaxTime()(Code) Gets the maximum time of an entry entry maximum time getMinTime public synchronized long getMinTime()(Code) Gets the minimum time of an entry entry minimum time getName public String getName()(Code) Gets the name of the current stat. stat name getTotalTime public synchronized long getTotalTime()(Code) Gets the total time of an entry entry total time incrementCacheHit public synchronized void incrementCacheHit()(Code) Increments an entry cache hit by one. incrementCount public synchronized void incrementCount()(Code) Increments an entry count by one. incrementError public synchronized void incrementError()(Code) Increments an entry error by one. merge public synchronized void merge(Stats anotherStat) throws Exception(Code) Adds the entries of another Stats object to this one. Parameters:   anotherStat - stat to merge with current stat throws:   Exception - if you try to merge a stat with itself multipleLineDisplay public String multipleLineDisplay()(Code) Displays the statistics information on multiple lines. a String containing the Stat output reset public synchronized void reset()(Code) Resets all entries to 0. singleLineDisplay public String singleLineDisplay()(Code) Displays the statistics information on a single line in the format: name count error cacheHit %hit minTime maxTime avgTime totalTime a String containing the Stat output toStringTable public String[] toStringTable()(Code) Get the stat information in the form of a String table. Format is: name count error cacheHit %hit minTime maxTime avgTime totalTime the String table corresponding to this stat updateTime public synchronized void updateTime(long time)(Code) Adds a new time sample for this entry. time is added to total time and both minTime and maxTime are updated if needed.
