|
*SUMMARY: Passing a RegExp object to a RegExp() constructor.
|
|
*This test arose from Bugzilla bug 61266. The ECMA3 section is:
|
|
*
|
|
* 15.10.4.1 new RegExp(pattern, flags)
|
|
*
|
|
* If pattern is an object R whose [[Class]] property is "RegExp" and
|
|
* flags is undefined, then let P be the pattern used to construct R
|
|
* and let F be the flags used to construct R. If pattern is an object R
|
|
* whose [[Class]] property is "RegExp" and flags is not undefined,
|
|
* then throw a TypeError exception. Otherwise, let P be the empty string
|
|
* if pattern is undefined and ToString(pattern) otherwise, and let F be
|
|
* the empty string if flags is undefined and ToString(flags) otherwise.
|
|
*
|
|
*
|
|
*The current test will check the first scenario outlined above:
|
|
*
|
|
* "pattern" is itself a RegExp object R
|
|
* "flags" is undefined
|
|
*
|
|
* We check that a new RegExp object obj2 defined from these parameters
|
|
* is morally the same as the original RegExp object obj1. Of course, they
|
|
* can't be equal as objects - so we check their enumerable properties...
|
|
*
|
|
* In this test, the initial RegExp object obj1 will not include a flag. This test is
|
|
* identical to test 15.10.4.1-1.js, except that here we use this syntax:
|
|
*
|
|
* obj2 = new RegExp(obj1, undefined);
|
|
*
|
|
* instead of:
|
|
*
|
|
* obj2 = new RegExp(obj1);
