Class ObjectMBean

    java.lang.Object
      org.mortbay.management.ObjectMBean

All Implemented Interfaces:
  DynamicMBean

Direct Known Subclasses:
  ContextHandlerMBean, HolderMBean, ServerMBean

    public class ObjectMBean

extends Object
implements 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.

Field Detail

### _managed

    protected Object _managed

Constructor Detail

### ObjectMBean

    public ObjectMBean(Object managedObject)

Method Detail

### mbeanFor

    public static Object mbeanFor(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.management.MyClassMBean
  - com.acme.util.management.BaseClassMBean
  - org.mortbay.management.ObjectMBean

  Parameters:
    `o` - The object
  Returns:
    A new instance of an MBean for the object or null.

  Specified by:
    `invoke` in interface `DynamicMBean`
  Throws:
    `MBeanException`

### defineAttribute

    public MBeanAttributeInfo defineAttribute(String name,
                                              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 the "Object","MBean" or "MObject" to indicate the method is on the object, the MBean or on the object but converted to an MBean, access is either "RW" or "RO".
