Class AbstractStatistic

java.lang.Object

java.lang.Thread

clazzfish.core.util.ShutdownHook

clazzfish.monitor.AbstractMonitor

clazzfish.jdbc.AbstractStatistic

All Implemented Interfaces:

Shutdownable, AbstractStatisticMBean, AbstractMonitorMBean, Runnable

Direct Known Subclasses:

SqlStatistic

public abstract class AbstractStatistic
extends AbstractMonitor
implements AbstractStatisticMBean

This was constructed as a thin layer around com.jamonapi.MonitorFactory for the needs of generating statistics. The reason for this layer is that sometimes you want to minimize the use of other libraries. So this implementation provides also an implementation if the JaMon library is missing.

Since:

0.9

Constructor Details

AbstractStatistic

protected AbstractStatistic(String rootLabel)

Instantiates a new profile statistic.

Parameters:

rootLabel - the root label

Method Details

reset

public void reset()

We can't reset all ProfileMonitors - we must keep the empty monitors with 0 hits to see which methods or constructors are never called.

Specified by:

reset in interface AbstractStatisticMBean

resetRootMonitor

protected void resetRootMonitor()

Resets the root monitor.

setMaxSize

public void setMaxSize(int size)

Here you can set the maximal size of the statistic entries.

Specified by:

setMaxSize in interface AbstractStatisticMBean

Parameters:

size - the new max size

getMaxSize

public int getMaxSize()

Gets the max size.
