[NumberUtils] Please add number <> byte[] methods -------------------------------------------------
Key: LANG-341 URL: https://issues.apache.org/jira/browse/LANG-341 Project: Commons Lang Issue Type: New Feature Reporter: Lilianne E. Blaze Hello, I need a set of methods to convert Long to or from a byte[] array, as if writing / reading from Data(Input/Output)Stream( ByteArray(Input/Output)Stream ). First, doing it with Streams seems a bit wasteful, second, it seems a pretty general use. Would it be possible to add something like that to, for example, org.apache.commons.lang.math.NumberUtils? Example code: static public long toLong(byte[] b) { return toLong(b, 0); } static public long toLong(byte[] b, int offset) { return (((long)b[offset] << 56) + ((long)(b[offset + 1] & 255) << 48) + ((long)(b[offset + 2] & 255) << 40) + ((long)(b[offset + 3] & 255) << 32) + ((long)(b[offset + 4] & 255) << 24) + ((b[offset + 5] & 255) << 16) + ((b[offset + 6] & 255) << 8) + ((b[offset + 7] & 255) << 0)); } static public byte[] longToByteArray(long l) { byte b[] = new byte[8]; longToByteArray(l, b, 0); return b; } static public void longToByteArray(long l, byte b[], int offset) { b[offset] = (byte)(l >>> 56); b[offset + 1] = (byte)(l >>> 48); b[offset + 2] = (byte)(l >>> 40); b[offset + 3] = (byte)(l >>> 32); b[offset + 4] = (byte)(l >>> 24); b[offset + 5] = (byte)(l >>> 16); b[offset + 6] = (byte)(l >>> 8); b[offset + 7] = (byte)(l >>> 0); } -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
