public bool IsCompleted(EventID id)
Parameters
ID of the event to query.
Returns
Type | Description |
|---|---|
| bool | True if the asynchronous operation has completed. |
Remarks
This method returns immediately and does not wait for the operation to complete. Use RadeonRaysContext.Flush to force the device implementation to start processing commands. Use IDeviceContext.Wait to busy-wait for a specific event.
using System.Threading;using Unity.Collections;using UnityEngine;using UnityEngine.LightTransport;IDeviceContext ctx = new RadeonRaysContext();ctx.Initialize();uint length = 8;var input = new NativeArray<byte>((int)length, Allocator.Persistent);for (int i = 0; i < length; ++i){ input[i] = (byte)i;}var output = new NativeArray<byte>((int)length, Allocator.Persistent);BufferID id = ctx.CreateBuffer(length, 1);var writeEvent = ctx.CreateEvent();ctx.WriteBuffer(id.Slice<byte>(), input, writeEvent);var readEvent = ctx.CreateEvent();ctx.ReadBuffer(id.Slice<byte>(), output, readEvent);bool flushOk = ctx.Flush();Assert.IsTrue(flushOk);input.Dispose();var watchDogTimeout = Time.realtimeSinceStartup + 5.0f;while (!ctx.IsCompleted(readEvent)){ Thread.Sleep(10); if (Time.realtimeSinceStartup > watchDogTimeout) Assert.IsTrue(false, "watchdog timeout");}// The event has completed.ctx.DestroyEvent(readEvent);ctx.DestroyEvent(writeEvent);ctx.DestroyBuffer(id);for (int i = 0; i < length; ++i) Assert.AreEqual((byte)i, output[i]);output.Dispose();ctx.Dispose();
