The "no copy buffer" version can be more efficient by only calling `Arrays.copyOf()` when hitting EOF. This avoids copying the byte array when it is completely filled: ``` public static byte[] readRange(final ReadableByteChannel input, final int len) throws IOException { final ByteBuffer b = ByteBuffer.allocate(len); while (b.hasRemaining()) { if (input.read(b) <= 0) { break; } } if (b.hasRemaining()) { // We hit EOF and read less bytes, return a smaller array than len return Arrays.copyOf(b.array(), b.position()); } else { return b.array(); } } -- This is an automated message from the Apache Git Service.
