Method Detail

getMBeanServer

public MBeanServer getMBeanServer()

Return the internal MBeanServer

getExistingMBeanServerConnection

public MBeanServerConnection getExistingMBeanServerConnection()

Specified by:

getExistingMBeanServerConnection in interface ConnectionSource

Returns:

existing connection, valid or not, may be null

getMBeanServerConnection

public MBeanServerConnection getMBeanServerConnection(boolean forceNew)

Description copied from interface: ConnectionSource

Return a valid MBeanServerConnection, making a new connection if necessary, or returning an existing one if still valid. Some implementations may choose to not allow creation of a new connection (when 'forceNew' is specified).

Should not be called frequently, as the check for validity will make a remote call.

An implementation may choose to ignore the 'forceNew' parameter and always return the same connection.

Specified by:

getMBeanServerConnection in interface ConnectionSource

Parameters:

forceNew - creates a new connection instead of reusing an existing one

Returns:

the connection, or null if a new one is not possible

getJMXConnector

public JMXConnector getJMXConnector(boolean forceNew)

Specified by:

getJMXConnector in interface ConnectionSource

Returns:

a JMXConnector or null if not appropriate
