All Implemented Interfaces:

javax.realtime.AllocationContext

@SCJAllowed(value=INFRASTRUCTURE)
final class PrivateMemory
extends ManagedMemory

This class cannot be directly instantiated by the application; hence there are no public constructors. Every Schedulable object is provided with one instance of PrivateMemory , its root private memory area. A schedulable object active within a private memory area can create nested private memory areas through the enterPrivateMemory method of ManagedMemory.

The rules for nested entering into a private memory are that the private memory area must be the current allocation context, and the calling schedulable object has to be the owner of the memory area. The owner of the memory area is defined to be the schedulable object that it was provided for.
