public interface MemoryManagerMXBean extends PlatformManagedObject
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 an MXBean that can be obtained by calling the ManagementFactory.getMemoryManagerMXBeans() method or from the platform MBeanServer method.

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