拦截Eclipse e4平台异常 [英] Intercepting Eclipse e4 platform exceptions

问题描述

使用Eclipse RCP 3.x，可以创建定制的AbstractStatusHandler来拦截平台异常。一种方法是，像这样重写ApplicationWorkbenchAdvisor类中的getWorkbenchErrorHandler（）方法：

Using Eclipse RCP 3.x, it is possible to create a custom AbstractStatusHandler to intercept platform exceptions. One way to do this, is to override the getWorkbenchErrorHandler() method in the ApplicationWorkbenchAdvisor class like this:

    @Override
    public synchronized AbstractStatusHandler getWorkbenchErrorHandler()
    {
        if (m_errorHandler == null)
        {
            m_errorHandler = new MyWorkbenchErrorHandler(this);
        }
        return m_errorHandler;
    }

在Eclipse论坛，stackoverflow和Lars Vogel中进行了大量研究之后Eclipse 4书，我无法找到使用e4的等效方法。

After doing a lot of research in Eclipse forums, stackoverflow and in the Lars Vogel Eclipse 4 book, I have not been able to find an equivalent way to do this using e4.

任何帮助将不胜感激。

推荐答案

您可以将我们自己的 IEventLoopAdvisor 放入上下文中。一个好地方是在生命周期处理程序中的 @PostContructCreate 上。

You can put our own IEventLoopAdvisor into the context. A good place to do this is on @PostContructCreate in your life cycle handler.

context.set(IEventLoopAdvisor.class, new IEventLoopAdvisor() {
        @Override
        public void eventLoopException(Throwable exception) {
            ... handle exception here ...
        }

        ...
    });

如果上下文中没有 IEventLoopAdvisor 该平台将使用默认值。您可以在 PartRenderingEngine （在编写第1102行时）中看到平台的操作方式：

If there is no IEventLoopAdvisor in the context the platform will use a default. You can see how the platform does this in PartRenderingEngine (at the time of writing on line 1102):
