Class RawMemoryRegion

java.lang.Object

javax.realtime.device.RawMemoryRegion

public class RawMemoryRegion
extends java.lang.Object

RawMemoryRegion is a tagging interface for objects that identify raw memory _regions_. It is returned by the RawMemoryRegionFactory.getRegion() methods of the raw memory region factory classes, and it is used with methods such as RawMemoryFactory.createRawByte(RawMemoryRegion, long, int, int) and RawMemoryFactory.createRawDouble(RawMemoryRegion, long, int, int) methods to identify the region from which the application wants to get an accessor instance.

This is distinct from the, similarly named PhysicalMemoryName class, which is used with memory area classes, specifically ImmortalPhysicalMemory and LTPhysicalMemory.

Since:

RTSJ 2.0
