单个输入流包含两个文件.我想分割这些文件 [英] Single inputstream containing two files. I want to split those files

问题描述

在Java中，我有一个inputstream(也许是sequenceinputstream)，其中包含多个文件.我想使用Java分隔这些文件. java中有可用的解决方案吗?

In java I'm having an inputstream (maybe sequenceinputstream) containing more than one file. I want to separate those files using java. Is there any solution available in java?

推荐答案

简单的答案是:您不能/不应该.

The simple answer is: you can't / shouldn't.

复杂的答案:如果您正在处理SequenceInputStream，则可以使用此反射技巧来访问基础流:

The complicated answer: in case you are dealing with a SequenceInputStream, you can access the underlying streams using this reflection hack:

@SuppressWarnings("unchecked")
public static Enumeration<InputStream> split(final SequenceInputStream sis){
    try{
        Field streamsEnumField =
            SequenceInputStream.class.getDeclaredField("e");
        streamsEnumField.setAccessible(true);
        return (Enumeration<InputStream>) streamsEnumField.get(sis);
    } catch(final Exception e){
        throw new IllegalStateException(e);
    }
}

但是我会非常谨慎地使用这样的东西.

But I would be very careful about using something like this.
