All Implemented Interfaces:

Serializable

Enclosing class:

RASM

Deprecated. Use StatelessDevice

public static class RASM.StatelessDevice

extends Instruction

Mark thread as stateless.

This sets an internal flag in the thread which allows state characterisation of the device to be optimised by saying that the device will never have any state.

In the implementation, this avoids a string copy and a hash-table lookup, as well as allowing an appreciable compression in the size of state vector generated. This instruction should only ever be used where the thread is known systematically to be statelss, as is the case with many of the devices in the standard library and some user-defined Green devices (like functions and tables.)

Also incorporates the action of the StaticStackBase instruction.
