Java注释处理：我怎么知道，如果一个圆是最后一个？ [英] Java annotation processing: how do I know if a round is the last one?

问题描述

延长当 AbstractProcessor ​​，有覆盖的init（...）一种可能性，但没有反其道而行之的方法，这将以后被称为全部轮进行了处理。

When extending AbstractProcessor, there is a possibility to override init(...), but there is no "opposite" method, which would be called after all rounds were processed.

这是一个问题：当你有追加每一轮的相同文件中收集到的信息，你就永远不能关闭文件，因为你永远不会知道什么时候在最后一个圆了。因此，该文件是永远不会关闭，仍然是空的。

This is a problem: when you have to append information collected during each round to same file, you just can't ever close the file, because you never get to know when the last round was. So, the file is never closed and remains empty.

使用shutdown钩也不起作用，钩永远不会被调用。

Using a shutdown hook doesn't work either, the hook is never called.

任何想法？

的<一个href=\"http://download.oracle.com/javase/6/docs/api/javax/annotation/processing/Processor.html#process%28java.util.Set,%20javax.annotation.processing.RoundEnvironment%29\"><$c$c>Processor.process方法包括类型的参数<一个href=\"http://download.oracle.com/javase/6/docs/api/javax/annotation/processing/RoundEnvironment.html\"><$c$c>RoundEnvironment.也许<一个href=\"http://download.oracle.com/javase/6/docs/api/javax/annotation/processing/RoundEnvironment.html#processingOver%28%29\"><$c$c>RoundEnvironment.processingOver方法能有所帮助。

The Processor.process method includes an argument of type RoundEnvironment. Perhaps the RoundEnvironment.processingOver method can be of help.
