javax.realtime.LTPhysicalMemory
java.lang.Object
An instance of LTPhysicalMemory allows objects to be allocated from
a range of physical memory with particular attributes, determined by
their memory type. This memory area has the same semantics
as ScopedMemory memory areas, and the same performance
restrictions as LTMemory.
Methods from LTPhysicalMemory should be overridden only by methods that
use super.

public LTPhysicalMemory(java.lang.Object type,

LTPhysicalMemory with the given parameters.
type - An instance of Object representing the type of
memory required (e.g., dma, shared) - used to define the base address
and control the mapping. If the required memory has more than one
attribute, type may be an array of objects. If type
is null or a reference to an array with no entries, any type of memory
is acceptable.size - The size of the area in bytes.
java.lang.SecurityException - Thrown if the application doesn't have
permissions to access physical memory or the given type of memory.
java.lang.IllegalArgumentException - Thrown if size is less than zero.
SizeOutOfBoundsException - Thrown if
the implementation detects size extends
beyond physically addressable memory.
UnsupportedPhysicalMemoryException - Thrown if the underlying
hardware does not support the given type, or if no matching
PhysicalMemoryTypeFilter has been registered with
the PhysicalMemoryManager.
