Description
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.
