## java.lang.management
Interface MemoryManagerMXBean

All Known Subinterfaces:
  GarbageCollectorMXBean

    public interface MemoryManagerMXBean

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:

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

  1.5
