Class ModelMBeanInfoSupport

All Implemented Interfaces:
Serializable, Cloneable, DescriptorRead, ModelMBeanInfo 
public class ModelMBeanInfoSupport
extends MBeanInfo
implements ModelMBeanInfo

This class represents the meta data for ModelMBeans. Descriptors have been added on the meta data objects.

Java resources wishing to be manageable instantiate the ModelMBean using the MBeanServer's createMBean method. The resource then sets the ModelMBeanInfo and Descriptors for the ModelMBean instance. The attributes and operations exposed via the ModelMBeanInfo for the ModelMBean are accessible from MBeans, connectors/adaptors like other MBeans. Through the Descriptors, values and methods in the managed application can be defined and mapped to attributes and operations of the ModelMBean. This mapping can be defined during development in a file or dynamically and programmatically at runtime.

Every ModelMBean which is instantiated in the MBeanServer becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBeanServer. A Java object cannot be registered in the MBeanServer unless it is a JMX compliant MBean. By instantiating a ModelMBean, resources are guaranteed that the MBean is valid. MBeanException and RuntimeOperationsException must be thrown on every public method. This allows for wrapping exceptions from distributed communications (RMI, EJB, etc.)

The serialVersionUID of this class is -1935722590756516193L.

Constructor Detail

ModelMBeanInfoSupport

public ModelMBeanInfoSupport​(ModelMBeanInfo mbi)

Constructs a ModelMBeanInfoSupport which is a duplicate of the given ModelMBeanInfo. The returned object is a shallow copy of the given object. Neither the Descriptor nor the contained arrays (ModelMBeanAttributeInfo[] etc) are cloned. This method is chiefly of interest to modify the Descriptor of the returned instance via setDescriptor without affecting the Descriptor of the original object.

Parameters:
mbi - the ModelMBeanInfo instance from which the ModelMBeanInfo being created is initialized.

ModelMBeanInfoSupport

public ModelMBeanInfoSupport​(String className,
                             String description,
                             ModelMBeanAttributeInfo[] attributes,
                             ModelMBeanConstructorInfo[] constructors,
                             ModelMBeanOperationInfo[] operations,
                             ModelMBeanNotificationInfo[] notifications)

Creates a ModelMBeanInfoSupport with the provided information, but the descriptor is a default. The default descriptor is: name=className, descriptorType="mbean", displayName=className, persistPolicy="never", log="F", visibility="1"

Parameters:
className - classname of the MBean
description - human readable description of the ModelMBean
attributes - array of ModelMBeanAttributeInfo objects which have descriptors
constructors - array of ModelMBeanConstructorInfo objects which have descriptors
operations - array of ModelMBeanOperationInfo objects which have descriptors
notifications - array of ModelMBeanNotificationInfo objects which have descriptors

ModelMBeanInfoSupport

public ModelMBeanInfoSupport​(String className,
                             String description,
                             ModelMBeanAttributeInfo[] attributes,
                             ModelMBeanConstructorInfo[] constructors,
                             ModelMBeanOperationInfo[] operations,
                             ModelMBeanNotificationInfo[] notifications,
                             Descriptor mbeandescriptor)

Creates a ModelMBeanInfoSupport with the provided information and the descriptor given in parameter.

Parameters:
className - classname of the MBean
description - human readable description of the ModelMBean
attributes - array of ModelMBeanAttributeInfo objects which have descriptors
constructors - array of ModelMBeanConstructorInfo objects which have descriptor
operations - array of ModelMBeanOperationInfo objects which have descriptor
notifications - array of ModelMBeanNotificationInfo objects which have descriptor
mbeandescriptor - descriptor to be used as the MBeanDescriptor containing MBean wide policy. If the descriptor is null, a default descriptor will be constructed. The default descriptor is: name=className, descriptorType="mbean", displayName=className, persistPolicy="never", log="F", visibility="1". If the descriptor does not contain all of these fields, the missing ones are added with these default values.
Throws:
RuntimeOperationsException - Wraps an IllegalArgumentException for invalid descriptor passed in parameter. (see getMBeanDescriptor for the definition of a valid MBean descriptor.)

Method Detail

clone

public Object clone()

Returns a shallow clone of this instance. Neither the Descriptor nor the contained arrays (ModelMBeanAttributeInfo[] etc) are cloned. This method is chiefly of interest to modify the Descriptor of the clone via setDescriptor without affecting the Descriptor of the original object.

Specified by:
clone in interface ModelMBeanInfo
Overrides:
clone in class MBeanInfo
Returns:
a shallow clone of this instance.

Cloneable

getDescriptor

public Descriptor getDescriptor​(String inDescriptorName)
                         throws MBeanException,
                                RuntimeOperationsException

Returns a Descriptor requested by name.

Parameters:
inDescriptorName - The name of the descriptor.
Returns:
Descriptor containing a descriptor for the ModelMBean with the same name. If no descriptor is found, null is returned.
Throws:
MBeanException - Wraps a distributed communication Exception.
RuntimeOperationsException - Wraps an IllegalArgumentException for null name.

ModelMBeanInfo.setDescriptor(javax.management.Descriptor, java.lang.String)

getConstructor

public ModelMBeanConstructorInfo getConstructor​(String inName)
                                         throws MBeanException,
                                                RuntimeOperationsException

Returns the ModelMBeanConstructorInfo requested by name. If no ModelMBeanConstructorInfo exists for this name null is returned.

Parameters:
inName - the name of the constructor.
Returns:
the constructor info for the named constructor, or null if there is none.
Throws:
MBeanException - Wraps a distributed communication Exception.
RuntimeOperationsException - Wraps an IllegalArgumentException for a null constructor name.

getDescriptor

public Descriptor getDescriptor()

Description copied from class: MBeanInfo

Get the descriptor of this MBeanInfo. Changing the returned value will have no affect on the original descriptor.
