All Known Subinterfaces:

GarbageCollectorMBean

public interface MemoryManagerMBean

The management interface for a memory manager. A memory manager manages one or more memory pools of the Java virtual machine.

A Java virtual machine has one or more memory managers. An instance implementing this interface is a managed bean (MBean) conforming to the JMX Instrumentation Specification. The MBean can be obtained by calling the ManagementFactory.getMemoryManagerMBeans() method. An application can monitor the instrumentation of a memory manager and manage certain characteristics in any of the following ways:

• Call the methods of the MBean directly.
• Go through the MBeanServer.
• Construct an MBean proxy and call the methods of the MBean proxy.

The ManagementFactory.getPlatformMBeanServer() method returns the platform MBeanServer registered with all platform MBeans.

The ObjectName for uniquely identifying the MBean for a memory manager within an MBeanServer is:

java.lang:type=MemoryManager,name=manager's name
