Class HeapImplMemoryMXBean

java.lang.Object

com.oracle.svm.core.genscavenge.HeapImplMemoryMXBean

All Implemented Interfaces:

MemoryMXBean, PlatformManagedObject, NotificationBroadcaster, NotificationEmitter

public final class HeapImplMemoryMXBean
extends Object
implements MemoryMXBean, NotificationEmitter

A MemoryMXBean for this heap. Note: This implementation is somewhat inefficient, in that each time it is asked for the current heap memory usage or non-heap memory usage, it uses the MemoryWalker.Visitor to walk all of memory. If someone asks for only the heap memory usage or the non-heap memory usage, the other kind of memory will still be walked. If someone asks for both the heap memory usage and the non-heap memory usage, all the memory will be walked twice.
