| 10 *SUMMARY: Passing a RegExp object to a RegExp() constructor. | |
| 11 *This test arose from Bugzilla bug 61266. The ECMA3 section is: | |
| 12 * | |
| 13 * 15.10.4.1 new RegExp(pattern, flags) | |
| 14 * | |
| 15 * If pattern is an object R whose [[Class]] property is "RegExp" and | |
| 16 * flags is undefined, then let P be the pattern used to construct R | |
| 17 * and let F be the flags used to construct R. If pattern is an object R | |
| 18 * whose [[Class]] property is "RegExp" and flags is not undefined, | |
| 19 * then throw a TypeError exception. Otherwise, let P be the empty string | |
| 20 * if pattern is undefined and ToString(pattern) otherwise, and let F be | |
| 21 * the empty string if flags is undefined and ToString(flags) otherwise. | |
| 22 * | |
| 23 * | |
| 24 *The current test will check the first scenario outlined above: | |
| 25 * | |
| 26 * "pattern" is itself a RegExp object R | |
| 27 * "flags" is undefined | |
| 28 * | |
| 29 * We check that a new RegExp object obj2 defined from these parameters | |
| 30 * is morally the same as the original RegExp object obj1. Of course, they | |
| 31 * can't be equal as objects - so we check their enumerable properties... | |
| 32 * | |
| 33 * In this test, the initial RegExp object obj1 will not include a | |
| 34 * flag. This test is identical to test 15.10.4.1-1.js, except that | |
| 35 * here we use this syntax: | |
| 36 * | |
| 37 * obj2 = new RegExp(obj1, undefined); | |
| 38 * | |
| 39 * instead of: | |
| 40 * | |
| 41 * obj2 = new RegExp(obj1); | |
