java.lang.Object
  com.sleepycat.db.MutexStats

public class MutexStats

extends Object

Statistics about mutexes in a Berkeley DB database environment, returned by Environment.getMutexStats(com.sleepycat.db.StatsConfig)

Method Summary

int	getMutexAlign() The mutex alignment, in bytes.
int	getMutexCount() The total number of mutexes configured.
int	getMutexFree() The number of mutexes currently available.
int	getMutexInuse() The number of mutexes currently in use.
int	getMutexInuseMax() The maximum number of mutexes ever in use.
int	getMutexTasSpins() The number of times test-and-set mutexes will spin without blocking.
int	getRegionNowait() The number of times that a thread of control was able to obtain the mutex region mutex without waiting.
int	getRegionWait() The number of times that a thread of control was forced to wait before obtaining the mutex region mutex.
int	getRegSize() The size of the mutex region, in bytes.
String	toString() For convenience, the MutexStats class has a toString method that lists all the data fields.
