Interface FrameworkMBean

All Known Implementing Classes:

Framework

public interface FrameworkMBean

This mbean provides access to the basic framework information:

• BundleInfo
• PackageInfo
• ServiceInfo

The idea underlying this is to provide both a reasonably fast way to access all the framework information, avoiding too much message-passing overhead, while at the same time provide console-friendly information.

Internally, implementations of Info objects include references to each other, so that with getBundleInfo() you get information, indirectly, of all the services and packages.

This mbean also dynamically registers mbeans representing those objects to ease-up direct usage by generic JMX mgmt consoles (such as Jconsole) that are not aware of the data types used. While CompositeDataTypes could be used (as in former JMood implementations), they are too cumbersome to use and place too much dependency on JMX.
