          Description

Interface Summary
CompositeData	The CompositeData interface specifies the behavior of a specific type of complex open data objects which represent composite data structures.
OpenMBeanAttributeInfo	Describes an attribute of an open MBean.
OpenMBeanConstructorInfo	Describes a constructor of an Open MBean.
OpenMBeanInfo	Describes an Open MBean: an Open MBean is recognized as such if its getMBeanInfo() method returns an instance of a class which implements the OpenMBeanInfo interface, typically OpenMBeanInfoSupport.
OpenMBeanOperationInfo	Describes an operation of an Open MBean.
OpenMBeanParameterInfo	Describes a parameter used in one or more operations or constructors of an open MBean.
TabularData	The TabularData interface specifies the behavior of a specific type of complex open data objects which represent tabular data structures.

 

Class Summary
ArrayType	The ArrayType class is the open type class whose instances describe all open data values which are n-dimensional arrays of open data values.
CompositeDataSupport	The CompositeDataSupport class is the open data class which implements the CompositeData interface.
CompositeType	The CompositeType class is the open type class whose instances describe the types of CompositeData values.
OpenMBeanAttributeInfoSupport	Describes an attribute of an open MBean.
OpenMBeanConstructorInfoSupport	Describes a constructor of an Open MBean.
OpenMBeanInfoSupport	The OpenMBeanInfoSupport class describes the management information of an open MBean: it is a subclass of MBeanInfo, and it implements the OpenMBeanInfo interface.
OpenMBeanOperationInfoSupport	Describes an operation of an Open MBean.
OpenMBeanParameterInfoSupport	Describes a parameter used in one or more operations or constructors of an open MBean.
OpenType	The OpenType class is the parent abstract class of all classes which describe the actual open type of open data values.
SimpleType	The SimpleType class is the open type class whose instances describe all open data values which are neither arrays, nor CompositeData values, nor TabularData values.
TabularDataSupport	The TabularDataSupport class is the open data class which implements the TabularData and the Map interfaces, and which is internally based on a hash map data structure.
TabularType	The TabularType class is the open type class whose instances describe the types of TabularData values.

 

Exception Summary
InvalidKeyException	This runtime exception is thrown to indicate that a method parameter which was expected to be an item name of a composite data or a row index of a tabular data is not valid.
InvalidOpenTypeException	This runtime exception is thrown to indicate that the open type of an open data value is not the one expected.
KeyAlreadyExistsException	This runtime exception is thrown to indicate that the index of a row to be added to a tabular data instance is already used to refer to another row in this tabular data instance.
OpenDataException	This checked exception is thrown when an open type, an open data or an open MBean metadata info instance could not be constructed because one or more validity constraints were not met.

 

Package javax.management.openmbean Description

Provides the open data types and Open MBean descriptor classes. An Open MBean is an MBean where the types of attributes and of operation parameters and return values are built using a small set of predefined Java classes. Open MBeans facilitate operation with remote management programs that do not necessarily have access to application-specific types, including non-Java programs.

Every MBean has an MBeanInfo with information about the MBean itself, and its attributes, operations, constructors, and notifications. In an Open MBean, this MBeanInfo implements the OpenMBeanInfo interface, usually by being an instance of OpenMBeanInfoSupport.

The attribute information returned by MBeanInfo.getAttributes for an Open MBean is an array of objects implementing OpenMBeanAttributeInfo, usually instances of OpenMBeanAttributeInfoSupport. In addition to the usual information about attributes, an OpenMBeanAttributeInfo specifies the OpenType of the attribute. The possible OpenType values are predefined, which is what ensures that remote managers will understand them.

Similar remarks apply to the parameter types of operations and constructors, and to the return types of operations.

There is a distinction between an attribute's Java language type, as returned by getType(), and its OpenType, as returned by getOpenType(). For example, if the Java language type is java.lang.String, the OpenType will be SimpleType.String. If the Java language type is CompositeData, the OpenType will be a CompositeType that describes the items in the CompositeData instances for the attribute.
