Class StatsImpl

java.lang.Object
  com.sun.appserv.management.j2ee.statistics.GetterInvocationHandler<T>
      com.sun.appserv.management.j2ee.statistics.MapGetterInvocationHandler<Statistic>
          com.sun.appserv.management.j2ee.statistics.StatsImpl

All Implemented Interfaces:

Serializable, InvocationHandler, Stats

public class StatsImpl
extends MapGetterInvocationHandler<Statistic>
implements Stats, Serializable

Generic implementation of Stats based on either a Map or a CompositeData. There are two ways to implement a specific type of Stats object:

• The subclass extends this base class, using getValue() to fetch the requested value from the Map maintained by this class.
• Create a proxy implementing the desired Stats subclass interface and use an instance of this class as the InvocationHandler.

In addition to the standard JSR 77 Stats interfaces, the following specific Stats interfaces are available:

• AltJDBCConnectionPoolStats
• AltServletStats
• ConnectionManagerStats
• ConnectionPoolStats
• ConnectorConnectionPoolStats
• EJBCacheStats
• EJBMethodStats
• EJBPoolStats
• HTTPListenerStats
• HTTPServiceVirtualServerStats
• KeepAliveStats
• ThreadPoolStats
• TransactionServiceStats
• WebModuleVirtualServerStats

Method Detail

getStatistic

public Statistic getStatistic(String statisticName)

Description copied from interface: Stats

Get a Statistic by name.

Specified by:

getStatistic in interface Stats

getStatisticNames

public String[] getStatisticNames()

Description copied from interface: Stats

Returns an array of Strings which are the names of the attributes from the specific Stats submodel that this object supports. Attributes named in the list must correspond to attributes that will return a Statistic object of the appropriate type which contains valid performance data. The return value of attributes in the Stats submodel that are not included in the statisticNames list must be null. For each name in the statisticNames list there must be one Statistic with the same name in the statistics list.

Specified by:

getStatisticNames in interface Stats

getStatistics

public Statistic[] getStatistics()

Description copied from interface: Stats

Returns an array containing all of the Statistic objects supported by this Stats object.

Specified by:

getStatistics in interface Stats
