|
|
* <p> A Java virtual machine has a single instance of the implementation
|
|
* class of this interface. This instance implementing this interface is
|
|
* an <a href="ManagementFactory.html#MXBean">MXBean</a>
|
|
* that can be obtained by calling
|
|
* the {@link ManagementFactory#getRuntimeMXBean} method or
|
|
* from the {@link ManagementFactory#getPlatformMBeanServer
|
|
* platform <tt>MBeanServer</tt>} method.
|
|
*
|
|
* <p>The <tt>ObjectName</tt> for uniquely identifying the MXBean for
|
|
* the runtime system within an MBeanServer is:
|
|
* <blockquote>
|
|
* {@link ManagementFactory#RUNTIME_MXBEAN_NAME
|
|
* <tt>java.lang:type=Runtime</tt>}
|
|
* </blockquote>
|
|
*
|
|
* It can be obtained by calling the
|
|
* {@link PlatformManagedObject#getObjectName} method.
|
|
*
|
|
* <p> This interface defines several convenient methods for accessing
|
|
* system properties about the Java virtual machine.
