Class StartsAndStopsRuntimeThreads

java.lang.Object

org.ek9lang.compiler.phase9.StartsAndStopsRuntimeThreads

All Implemented Interfaces:

Predicate<IRInstr>

public final class StartsAndStopsRuntimeThreads
extends Object
implements Predicate<IRInstr>

THE calls that start runtime threads and finish only once every one of them has stopped (EK9_NATIVE_CYCLE_COLLECTOR_DESIGN.md §13.11, T10): a server's accept, acceptUntilComplete, serve and serveUntilComplete return after shutting down the scheduler they started, and an async pipeline's Ek9Async.create() begins the statement whose close() drains its workers and does the same. When the scope holding such a call ends, the work of every thread it started is done, so AfterThreadsSafePoints puts a SAFE_POINT after_threads there. Signals.register is not one: its dispatcher never stops. The front end's IsThreadSpawningCall asks a different question - which calls run a handler on another thread - for E08251. Stateless: hold one.
