Methods Summary
public static int	convert2Int(byte[] hex) Convert 4 hex digits to an int, and return the number of converted bytes. param hex Byte array containing exactly four hexadecimal digits exception IllegalArgumentException if an invalid hexadecimal digit is included // Code from Ajp11, from Apache's JServ // assert b.length==4 // assert valid data int len; if(hex.length < 4 ) return 0; if( DEC[hex[0]]<0 ) throw new IllegalArgumentException(ERROR_BAD_CHARACTER_IN_HEX_STRING); len = DEC[hex[0]]; len = len << 4; if( DEC[hex[1]]<0 ) throw new IllegalArgumentException(ERROR_BAD_CHARACTER_IN_HEX_STRING); len += DEC[hex[1]]; len = len << 4; if( DEC[hex[2]]<0 ) throw new IllegalArgumentException(ERROR_BAD_CHARACTER_IN_HEX_STRING); len += DEC[hex[2]]; len = len << 4; if( DEC[hex[3]]<0 ) throw new IllegalArgumentException(ERROR_BAD_CHARACTER_IN_HEX_STRING); len += DEC[hex[3]]; return len;
private static char	convertDigit(int value) [Private] Convert the specified value (0 .. 15) to the corresponding hexadecimal digit. param value Value to be converted value &= 0x0f; if (value >= 10) return ((char) (value - 10 + 'a")); else return ((char) (value + '0"));
public static byte[]	decode(java.lang.String digits) Convert a String of hexadecimal digits into the corresponding byte array by encoding each two hexadecimal digits as a byte. param digits Hexadecimal digits representation exception IllegalArgumentException if an invalid hexadecimal digit is found, or the input string contains an odd number of hexadecimal digits ByteArrayOutputStream baos = new ByteArrayOutputStream(); for (int i = 0; i < digits.length(); i += 2) { char c1 = digits.charAt(i); if ((i+1) >= digits.length()) throw new IllegalArgumentException (ERROR_ODD_NUMBER_OF_DIGITS); char c2 = digits.charAt(i + 1); byte b = 0; if ((c1 >= '0") && (c1 <= '9")) b += ((c1 - '0") * 16); else if ((c1 >= 'a") && (c1 <= 'f")) b += ((c1 - 'a" + 10) * 16); else if ((c1 >= 'A") && (c1 <= 'F")) b += ((c1 - 'A" + 10) * 16); else throw new IllegalArgumentException (ERROR_BAD_CHARACTER_IN_HEX_STRING); if ((c2 >= '0") && (c2 <= '9")) b += (c2 - '0"); else if ((c2 >= 'a") && (c2 <= 'f")) b += (c2 - 'a" + 10); else if ((c2 >= 'A") && (c2 <= 'F")) b += (c2 - 'A" + 10); else throw new IllegalArgumentException (ERROR_BAD_CHARACTER_IN_HEX_STRING); baos.write(b); } return (baos.toByteArray());
public static java.lang.String	encode(byte[] bytes) Convert a byte array into a printable format containing a String of hexadecimal digit characters (two per byte). param bytes Byte array representation StringBuffer sb = new StringBuffer(bytes.length * 2); for (int i = 0; i < bytes.length; i++) { sb.append(convertDigit((int) (bytes[i] >> 4))); sb.append(convertDigit((int) (bytes[i] & 0x0f))); } return (sb.toString());
public boolean	equals(java.lang.Object object) //TODO: Is this good enough? String s1 = object.toString(); String s2 = this.toString(); return s1.equals(s2);
public byte[]	getBytes() return m_value;
public int	hashCode() //TODO: How do we hash this? return super.hashCode();
public java.lang.String	toString() return encode(m_value);
