<DL>
<DD>Translate the given <code>String</code> into a <code>int []</code>
 representing the pattern matchable by this class.
 <br>
 This function translates a <code>String</code> into an int array
 converting the special '*' and '\' characters.
 <br>
 Here is how the conversion algorithm works:
 <ul>
   <li>The '*' character is converted to MATCH_FILE, meaning that zero
        or more characters (excluding the path separator '/') are to
        be matched.</li>
   <li>The '**' sequence is converted to MATCH_PATH, meaning that zero
       or more characters (including the path separator '/') are to
        be matched.</li>
   <li>The '\' character is used as an escape sequence ('\*' is
       translated in '*', not in MATCH_FILE). If an exact '\' character
       is to be matched the source string must contain a '\\'.
       sequence.</li>
 </ul>
 When more than two '*' characters, not separated by another character,
 are found their value is considered as '**' (MATCH_PATH).
 <br>
 The array is always terminated by a special value (MATCH_END).
 <br>
 All MATCH* values are less than zero, while normal characters are equal
 or greater.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>data</CODE> - The string to translate.<DT><B>Returns:</B><DD>The encoded string as an int array, terminated by the MATCH_END
         value (don't consider the array length).<DT><B>Throws:</B><DD><CODE>NullPointerException</CODE> - If data is null.</DL>
