Package javax.management.openmbean

Provides the data types and descriptor classes for the Open MBeans.

Interface Summary

CompositeData Provides an interface to a composite data structure, in order to aid interoperability.
TabularData Provides an interface to a specific type of composite data structure, where keys (the columns) map to the CompositeData objects that form the rows of the table.

Class Summary

ArrayType The open type descriptor for arrays of open data values.
CompositeDataSupport Provides an implementation of the CompositeData interface.
CompositeType The open type descriptor for instances of the CompositeData class.
OpenType The superclass of all open types, which describe the applicable data values for open MBeans.
SimpleType The open type descriptor for data values that are members of one of the simple types (such as an integer or a string).
TabularType The open type descriptor for instances of the TabularData class.

Exception Summary

InvalidKeyException Thrown when an invalid key (a field name or row index) is passed to a method of the CompositeData or TabularData classes.
OpenDataException Thrown when an instance of one of the open types, open data objects or open metadata information objects could not be created due to invalid construction parameters.
Provides the data types and descriptor classes for the Open MBeans. Open MBeans are provided in order to aid interoperability with non-Java management systems. Unlike normal MBeans, which make use of any Java data type, Open MBeans use a restricted set of types which can then be mapped over remote connections, including to non-Java systems.

Normal MBeans are described using an instance of MBeanInfo with appropriate representations of the attributes, constructors and operators associated with the bean. Open MBeans are described in the same way, but by using subtypes of these entities, which type the bean data using instances of OpenType. Open types differ from Java types, and are explicitly specified in order to obtain interoperability with other systems.
