Class StopwatchMXBeanImpl

java.lang.Object
  org.javasimon.jmx.AbstractSimonMXBeanImpl
      org.javasimon.jmx.StopwatchMXBeanImpl

All Implemented Interfaces:: SimonSuperMXBean, StopwatchMXBean

public class StopwatchMXBeanImpl
extends AbstractSimonMXBeanImpl
implements StopwatchMXBean
extends AbstractSimonMXBeanImpl
implements StopwatchMXBean

MX Bean representing a particular Stopwatch. It is not created by default when JMX is activated - it must be created explicitely. JmxRegisterCallback can be used to automate this.

Class can be subclassed to override default behavior if desired, stopwatch is declared protected for this reason.

Author:: Richard "Virgo" Richter

Field Summary
`protected Stopwatch`	`stopwatch` Wrapped `Stopwatch` instance - protected for subclasses.

Constructor Summary
`StopwatchMXBeanImpl(Stopwatch stopwatch)` Creates the MX bean for the provided Stopwatch.

Method Summary
`void`	`addTime(long ns)` Adds split time in nanoseconds to total time of the stopwatch.
`long`	`getActive()` Returns current number of measured splits (concurrently running).
`long`	`getCounter()` Returns usage count of the stopwatch.
`long`	`getLast()` Returns value of the last added split - wheter it was added directly or with stop method.
`String`	`getLastAsString()` Returns value of the last added split as formatted string.
`long`	`getMax()` Returns maximal time split value in nanoseconds.
`long`	`getMaxActive()` Returns peek value of active concurrent splits.
`long`	`getMaxActiveTimestamp()` Retruns ms timestamp when the last peek of the active split count occured.
`long`	`getMaxTimestamp()` Returns ms timestamp when the max value was measured.
`double`	`getMean()` Returns mean value (average) of all measured values.
`long`	`getMin()` Returns minimal time split value in nanoseconds.
`long`	`getMinTimestamp()` Returns ms timestamp when the min value was measured.
`double`	`getStandardDeviation()` Returns standard deviation for all measured values.
`long`	`getTotal()` Returns total sum of all split times in nanoseconds.
`String`	`getType()` Returns Simon type used as a property in the `ObjectName`.
`double`	`getVariance()` Returns unbiased estimate of the population variance.
`double`	`getVarianceN()` Returns variance value of all measured values (entire population).
`StopwatchSample`	`sample()` Samples Simon values and returns them in a Java Bean derived from Sample interface.
`StopwatchSample`	`sampleAndReset()` Samples Simon values and returns them in a Java Bean derived from Sample interface and resets the Simon.
`protected Simon`	`simon()` Returns the wrapped Simon.
