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.)

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 viasetDescriptor
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 MBeandescription
- human readable description of the ModelMBeanattributes
- array of ModelMBeanAttributeInfo objects which have descriptorsconstructors
- array of ModelMBeanConstructorInfo objects which have descriptorsoperations
- array of ModelMBeanOperationInfo objects which have descriptorsnotifications
- 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 MBeandescription
- human readable description of the ModelMBeanattributes
- array of ModelMBeanAttributeInfo objects which have descriptorsconstructors
- array of ModelMBeanConstructorInfo objects which have descriptoroperations
- array of ModelMBeanOperationInfo objects which have descriptornotifications
- array of ModelMBeanNotificationInfo objects which have descriptormbeandescriptor
- 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. (seegetMBeanDescriptor
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 viasetDescriptor
without affecting the Descriptor of the original object.- Specified by:
clone
in interfaceModelMBeanInfo
- Overrides:
clone
in classMBeanInfo
- Returns:
- a shallow clone of this instance.
- See Also:
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.- See Also:
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.- Specified by:
getDescriptor
in interfaceDescriptorRead
- Overrides:
getDescriptor
in classMBeanInfo
- Returns:
- a descriptor that is either immutable or a copy of the original.
