Imports
java.util.Map, java.lang.reflect.*, org.glassfish.external.statistics.AverageRangeStatistic
An implementation of AverageRangeStatistic that provides ways to change the state externally through mutators. Convenience class that is useful for components that gather the statistical data. By merely changing the count (which is a mandatory measurement), rest of the statistical information could be deduced.

public Object invoke(Object proxy, Method method, Object[] args) throws Throwable

Implements java.lang.reflect.InvocationHandler.invoke.

Doc from java.lang.reflect.InvocationHandler.invoke.

Processes a method invocation on a proxy instance and returns the result. This method will be invoked on an invocation handler when a method is invoked on a proxy instance that it is associated with.

Exceptions
Throwable:
the exception to throw from the method invocation on the proxy instance. The exception's type must be assignable either to any of the exception types declared in the throws clause of the invoked method or to the unchecked exception types java.lang.RuntimeException or java.lang.Error. If a checked exception is thrown by this method that is not assignable to any of the exception types declared in the throws clause of the invoked method, then an UndeclaredThrowableException containing the exception that was thrown by this method will be thrown by the method invocation on the proxy instance.

toStringback to summary
public synchronized String toString()

Overrides org.glassfish.external.statistics.impl.StatisticImpl.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.
