用InputStream包装ByteBuffer [英] Wrapping a ByteBuffer with an InputStream

问题描述

我有一个采用InputStream并从中读取数据的方法.我也想将此方法与ByteBuffer一起使用.有没有包装ByteBuffer的方法，以便可以将其作为流进行访问?

I have a method that takes an InputStream and reads data from it. I would like to use this method with a ByteBuffer also. Is there a way to wrap a ByteBuffer so it can be accessed as a stream?

推荐答案

JDK中什么也没有，但是有很多实现，对于ByteBufferInputStream来说，它是google的.基本上，它们包装一个或多个ByteBuffer并跟踪其中的索引，该索引记录已读取的数量.像这样的出现了很多，但显然是越野车，请参见 @Mike Houston的改进版本答案).

Nothing in the JDK, but there are lots of implementations out there, google for ByteBufferInputStream. Basically they wrap one or more ByteBuffers and keep track of an index into them that records how much has already been read. Something like this comes up a lot, but apparently is buggy, see @Mike Houston's answer for an improved version).
