Class OpenMBean

java.lang.Object

org.granite.jmx.OpenMBean

All Implemented Interfaces:

DynamicMBean

public class OpenMBean
extends Object
implements DynamicMBean

The OpenMBean class wraps an instance of any bean and introspects its properties and methods for MBeanAttributes and MBeanOperations. It implements all functionalities required by a DynamicMBean and returns an OpenMBeanInfo object.

Limitations:

• only attributes and operations are supported (no contructor and no notification),
• only SimpleType and ArrayType are supported (no composite type).

Constructor Detail

OpenMBean

protected OpenMBean()

Creates a new OpenMBean instance and instrospects its child class for attributes and operations.

Method Detail

createMBean

public static OpenMBean createMBean(Object instance)

Creates a new OpenMBean by introspecting and wrapping the instance parameter. This method search for an interface named instance.getClass().getSimpleName() + "MBean" and, if it finds it, uses it for introspection. Otherwise, the class of the instance object is used instead.

Parameters:

instance - an instance of a bean to introspect.

Returns:

a new OpenMBean instance that wraps the instance bean.

createMBean

public static OpenMBean createMBean(Class<?> beanClass,
                    Object instance)

Creates a new OpenMBean by introspecting the beanClass parameter and wrapping the instance parameter.

Parameters:

beanClass - a class (or interface) used for introspection.

instance - the bean to encapsulate.

Returns:

a new OpenMBean instance that wraps the instance bean.

Throws:

IllegalArgumentException - if instance is not an instance of beanClass.
