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 {@link ManagementFactory#getMemoryManagerMXBeans} method or from the {@link ManagementFactory#getPlatformMBeanServer platform MBeanServer} method.

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