Method Summary

Methods

Modifier and Type	Method and Description
static MBeanServer	getMBeanServer() Returns the first registered MBean server, or the platform MBean server if there is none.
static boolean	isRegistered(String objectName) Returns true if an MBean identified by the specified object name is already registered with the first MBean server, or the platform MBean server if there is no explicitly registered MBean server; false otherwise.
static <T> boolean	registerMBean(String objectName, T mbean) Registers the given MBean under the given object name to the first registered MBean server, or the platform MBean server if there is no explicitly registered MBean server.
static <T> boolean	unregisterMBean(String objectName) Unregisters the MBean under the given object name to the first MBean server, or the platform MBean server if there is no explicitly registered MBean server.
static MBeans	valueOf(String name) Returns the enum constant of this type with the specified name.
static MBeans[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static MBeans[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (MBeans c : MBeans.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static MBeans valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

registerMBean

public static <T> boolean registerMBean(String objectName,
                        T mbean)
                             throws MBeanRegistrationException

Registers the given MBean under the given object name to the first registered MBean server, or the platform MBean server if there is no explicitly registered MBean server.

Returns:

true if the registration succeeded, or false if an MBean already exists under the given object name.

Throws:

MBeanRegistrationException - The preRegister (MBeanRegistration interface) method of the MBean has thrown an exception. The MBean will not be registered.

unregisterMBean

public static <T> boolean unregisterMBean(String objectName)
                               throws MBeanRegistrationException

Unregisters the MBean under the given object name to the first MBean server, or the platform MBean server if there is no explicitly registered MBean server.

Returns:

true if the unregistration succeeded, or false if the MBean doesn't exist under the given object name.

Throws:

MBeanRegistrationException - Wraps exceptions thrown by the preRegister(), preDeregister() methods of the MBeanRegistration interface.

isRegistered

public static boolean isRegistered(String objectName)

Returns true if an MBean identified by the specified object name is already registered with the first MBean server, or the platform MBean server if there is no explicitly registered MBean server; false otherwise.

getMBeanServer

public static MBeanServer getMBeanServer()

Returns the first registered MBean server, or the platform MBean server if there is none.
