public class ObjectMBean
extends java.lang.Object
implements javax.management.DynamicMBean

ObjectMBean. A dynamic MBean that can wrap an arbitary Object instance. the attributes and methods exposed by this bean are controlled by the merge of property bundles discovered by names related to all superclasses and all superinterfaces. Attributes and methods exported may be "Object" and must exist on the wrapped object, or "MBean" and must exist on a subclass of OBjectMBean or "MObject" which exists on the wrapped object, but whose values are converted to MBean object names.

ObjectMBean

public ObjectMBean(java.lang.Object managedObject)

Method Detail

mbeanFor

public static java.lang.Object mbeanFor(java.lang.Object o)

Create MBean for Object. Attempts to create an MBean for the object by searching the package and class name space. For example an object of the type

 class com.acme.MyClass extends com.acme.util.BaseClass implements com.acme.Iface
 

Then this method would look for the following classes:

• com.acme.jmx.MyClassMBean
• com.acme.util.jmx.BaseClassMBean
• org.eclipse.jetty.jmx.ObjectMBean

Parameters:

o - The object

Returns:

A new instance of an MBean for the object or null.

                                                  java.lang.String metaData)

Define an attribute on the managed object. The meta data is defined by looking for standard getter and setter methods. Descriptions are obtained with a call to findDescription with the attribute name.

Parameters:

name -

metaData - "description" or "access:description" or "type:access:description" where type is one of:

• "Object" The field/method is on the managed object.
• "MBean" The field/method is on the mbean proxy object
• "MObject" The field/method is on the managed object and value should be converted to MBean reference
• "MMBean" The field/method is on the mbean proxy object and value should be converted to MBean reference

the access is either "RW" or "RO".
