有一个简单的“三通”过滤器Java流？ [英] Is there a simple “tee” filter for Java streams?

问题描述

有关调试效果影响不大，我想转储输出流的内容到一个文件，而对其进行处理。流由 org.xml.sax.XMLReader中解析，这将comsume数据。

For debugging purpouses I would like to dump the content of an output stream into a file while it is processed. The stream is parsed by org.xml.sax.XMLReader which will comsume the data.

我会GESS人需要一个过滤器，归档此，写我的一个自我之前，我想问问，如果有一个现成的版本，媒体链接。

I would gess one need a filter to archive this and before writing one my self I wanted to ask if there is a ready made version allready.

更新：

如果HABE提到，我的工作在Android上。

Should habe mentioned that I work on Android.

我有什么：

        final org.apache.http.HttpEntity responseEntity = response.getEntity ();
        final java.io.InputStream content = responseEntity.getContent ();
        final java.io.InputStreamReader contentReader =
           new java.io.InputStreamReader (content, "UTF-8");

所以，我有一个的java.io.InputStream 和 InputStreamReader的。

推荐答案

不是很现成推出，但是的这可能会感兴趣。有在实施例中一个TeeOutputStream实施

Not quite a ready rolled one, but this might be of interest. There is a TeeOutputStream implementation in the examples.
