ThreadPool (TotalCrossSDK 4.9.13 API)

java.lang.Object
- totalcross.util.concurrent.ThreadPool

```
public class ThreadPool
extends java.lang.Object
```
Pool that executes each submitted task using one of possibly several pooled threads.

Thread pools address two different problems: they usually provide improved performance when executing large numbers of asynchronous tasks, due to reduced per-task invocation overhead, and they provide a means of bounding and managing the resources, including threads, consumed when executing a collection of tasks.

Since:

TotalCross 4.3.9
