Real-Time Java™ Platform Programming

Asynchronous Interrupt Firing

The RTSJ provides three ways to raise an AIE. The interrupt method on RealtimeThread throws a generic AIE into the thread, the fire method on AsynchronouslyInterruptedException causes an AIE that is directed at a particular method, and at an assigned moment a Timed object throws an AIE at the run method it is given. (A thread can also just throw an AIE at itself, but then it isn't actually asynchronous.)

The Timed Class

Real-time applications frequently contain specifications like

Wait 200 milliseconds for a response, then stop the process and initiate recovery

or

Spend up to 1022 microseconds refining the computation, take the best result, and pass it to the next step in the computation

or

The thread should not ...
