Examples of java.lang.management.MemoryManagerMXBean

java.lang.management.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 {@link ManagementFactory#getMemoryManagerMXBeans} method orfrom the {@link ManagementFactory#getPlatformMBeanServer platform MBeanServer} method.
The ObjectName for uniquely identifying the MXBean for a memory manager within an MBeanServer is:
{@link ManagementFactory#MEMORY_MANAGER_MXBEAN_DOMAIN_TYPE java.lang:type=MemoryManager},name=manager's name
