java.lang.Object
   java.lang.VMMemoryManager

VMMemoryManager
final class VMMemoryManager (Code)
Provides the methods to interact with VM Memory Manager that are used by different classes from the java.lang package, such as Object, System, Runtime.

This class must be implemented according to the common policy for porting interfaces - see the porting interface overview for more detailes.
