Minor Description
I am looking for an implementation withe the following method signature:
public static byte[] readFully(final InputStream input, long length) throws IOException
I have needed this when parsing different protocols. For example, if the protocol has a fixed-length header with 40 bytes, I may just want to instantiate the small buffer with the entire header and then pick it apart. In my implementation of my business logic, if the header cannot be read in then it should throw an exception for being malformed.
