/**
 * Represents a clean way to handoff evaluation of some work to an executor associated
 * with a node's lifetime.
 * 

* There is no transfer of execution to the parallel class hierarchy. *

* Classes, such as Instance, that are themselves instantiated on the correct ClassLoader, utilise this class * to ensure the lifetime of any thread evaluating one of its method invocations matches the lifetime of the class itself. * Since they are instantiated on the correct ClassLoader, sharing only the interface, there is no serialization necessary. */ public interface IIsolatedExecutor { interface CallableNoExcept extends Callable { O call(); } interface SerializableRunnable extends Runnable, Serializable {} interface SerializableSupplier extends Supplier, Serializable {} interface SerializableCallable extends CallableNoExcept, Serializable {} interface SerializableConsumer extends Consumer, Serializable {} interface SerializableBiConsumer extends BiConsumer, Serializable {} interface TriConsumer { void accept(I1 i1, I2 i2, I3 i3); } interface SerializableTriConsumer extends TriConsumer, Serializable { } interface DynamicFunction { IO2 apply(IO2 i); } interface SerializableDynamicFunction extends DynamicFunction, Serializable {} interface SerializableFunction extends Function, Serializable {} interface SerializableBiFunction extends BiFunction, Serializable {} interface TriFunction { O apply(I1 i1, I2 i2, I3 i3); } interface SerializableTriFunction extends Serializable, TriFunction {} interface QuadFunction { O apply(I1 i1, I2 i2, I3 i3, I4 i4); } interface SerializableQuadFunction extends Serializable, QuadFunction {} interface QuintFunction { O apply(I1 i1, I2 i2, I3 i3, I4 i4, I5 i5); } interface SerializableQuintFunction extends Serializable, QuintFunction {} default IIsolatedExecutor with(ExecutorService executor) { throw new UnsupportedOperationException(); } default Executor executor() { throw new UnsupportedOperationException(); } Future shutdown(); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ CallableNoExcept> async(CallableNoExcept call); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ CallableNoExcept sync(CallableNoExcept call); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ CallableNoExcept> async(Runnable run); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ Runnable sync(Runnable run); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ Function> async(Consumer consumer); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ Consumer sync(Consumer consumer); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ BiFunction> async(BiConsumer consumer); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ BiConsumer sync(BiConsumer consumer); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ TriFunction> async(TriConsumer consumer); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ TriConsumer sync(TriConsumer consumer); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ Function> async(Function f); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ Function sync(Function f); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ BiFunction> async(BiFunction f); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ BiFunction sync(BiFunction f); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ TriFunction> async(TriFunction f); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ TriFunction sync(TriFunction f); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ QuadFunction> async(QuadFunction f); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ QuadFunction sync(QuadFunction f); /** * Convert the execution to one performed asynchronously on the IsolatedExecutor, returning a Future of the execution result */ QuintFunction> async(QuintFunction f); /** * Convert the execution to one performed synchronously on the IsolatedExecutor */ QuintFunction sync(QuintFunction f); }
