Class PhysicalMemorySelector

java.lang.Object

javax.realtime.memory.PhysicalMemorySelector

public class PhysicalMemorySelector
extends java.lang.Object

Provides characteristics both for physical memory, used to select a memory range from a memory module, and for virtual memory to be used for setting the characteristics of the mapped pages.

Constructor Detail

PhysicalMemorySelector

public PhysicalMemorySelector(PhysicalMemoryCharacteristic[] request,
                              PhysicalMemoryCharacteristic[] reject,
                              PhysicalMemorySelector.CachingBehavior caching,
                              PhysicalMemorySelector.PagingBehavior paging)

Creates a selector object for obtaining physical memory objects. The arguments are used to select the desired memory type.

Parameters:

request - characteristics that are required

reject - characteristics that should apply to the object

caching - the required caching behavior

paging - the required paging behavior
