41 * ECMA Section: 15.6.4.9
42 * Description: Based on ECMA 2 Draft 7 February 1999
44 * Author: christine@netscape.com
45 * Date: 19 February 1999
49 * String.match( regexp )
51 * If regexp is not an object of type RegExp, it is replaced with result
52 * of the expression new RegExp(regexp). Let string denote the result of
53 * converting the this value to a string. If regexp.global is false,
54 * return the result obtained by invoking RegExp.prototype.exec (see
55 * section 15.7.5.3) on regexp with string as parameter.
57 * Otherwise, set the regexp.lastIndex property to 0 and invoke
58 * RegExp.prototype.exec repeatedly until there is no match. If there is a
59 * match with an empty string (in other words, if the value of
60 * regexp.lastIndex is left unchanged) increment regexp.lastIndex by 1.
61 * The value returned is an array with the properties 0 through n-1
62 * corresponding to the first element of the result of each matching
63 * invocation of RegExp.prototype.exec.
65 * Note that the match function is intentionally generic; it does not
66 * require that its this value be a string object. Therefore, it can be
67 * transferred to other kinds of objects for use as a method.
