                           java.lang.OutOfMemoryError

Add new constraints to a physical memory request.

Parameters:

request - null or PhysicalMemoryRequest containing the previously parsed constraints.

Throws:

java.lang.SecurityException - Thrown if application doesn't have permissions to access physical memory, the specified range of addresses, or the given type of memory.

javax.realtime.OffsetOutOfBoundsException - Thrown if the address is invalid.

javax.realtime.SizeOutOfBoundsException - Thrown if the size is negative or extends into an invalid range of memory.

javax.realtime.UnsupportedPhysicalMemoryException - Thrown if the underlying hardware does not support the given type, or if no matching PhysicalMemoryTypeFilter has been registered with the PhysicalMemoryManager.

javax.realtime.MemoryTypeConflictException - Thrown if the specified base does not point to memory that matches the request type, or if type specifies incompatible memory attributes.

java.lang.OutOfMemoryError - Thrown if the requested type of memory exists, but there is not enough of it free to satisfy the request.
