我怎样才能DECOM preSS与升压瘪数据的载体？ [英] How can I decompress a vector of deflated data with Boost?

问题描述

我有一个包含zlib的-COM pressed（瘪）数据的载体。我想用DECOM Boost的 filtering_istream preSS它。只有一个在其网站上，其上的数据的一个流上进行操作（而不是一个矢量，我有）的例子。

I have a vector that contains zlib-compressed (deflated) data. I would like to decompress it with Boost's filtering_istream. There is only one example on their site, which operates on a stream of data (as opposed to a vector that I have).

vector<char> compressed_buffer;
compressed_buffer.resize(cdh.length);
file.read(&compressed_buffer[0], cdh.length);

filtering_istream in;
in.push(zlib_decompressor());
in.push(something(compressed_data)); // what should "something" be?

我想获得uncom pressed数据作为载体为好。我怎样才能做到这一点？

I would like to get the uncompressed data as a vector as well. How can I do this?

推荐答案

怎么样的的 array_source ？

How about an array_source?

in.push(array_source(&*compressed_data.begin(), &*compressed_data.end()));

然后使用的boost :: iostream的副本:: 与的std :: insert_iterator 来的结果字符推入一个新的载体。

Then use boost::iostreams::copy with a std::insert_iterator to push the result characters into a new vector.
