getInputStreamAsByteArray

static byte [] de.alysis.r.submit.model.SubmitUtils.getInputStreamAsByteArray (  InputStream  stream, int  length )  throws IOException [static, protected]   Returns the given input stream's contents as a byte array. If a length is specified (ie. if length != -1), only length bytes are returned. Otherwise all bytes in the stream are returned. Note this doesn't close the stream. Exceptions: IOException  if a problem occured reading the stream. { byte[] contents; if (length == -1) { contents = new byte[0]; int contentsLength = 0; int bytesRead = -1; do { int available = stream.available(); // resize contents if needed if (contentsLength + available > contents.length) { System.arraycopy(contents, 0, contents = new byte[contentsLength + available], 0, contentsLength); } // read as many bytes as possible bytesRead = stream.read(contents, contentsLength, available); if (bytesRead > 0) { // remember length of contents contentsLength += bytesRead; } } while (bytesRead > 0); // resize contents if necessary if (contentsLength < contents.length) { System.arraycopy(contents, 0, contents = new byte[contentsLength], 0, contentsLength); } } else { contents = new byte[length]; int len = 0; int readSize = 0; while ((readSize != -1) && (len != length)) { // See PR 1FMS89U // We record first the read size. In this // case len is the actual read size. len += readSize; readSize = stream.read(contents, len, length - len); } } return contents; }
