Feature #7394 ยป enumerable_find_noncallable.patch
| enum.c | ||
|---|---|---|
|
*
|
||
|
* Passes each entry in <i>enum</i> to <em>block</em>. Returns the
|
||
|
* first for which <em>block</em> is not false. If no
|
||
|
* object matches, calls <i>ifnone</i> and returns its result when it
|
||
|
* is specified, or returns <code>nil</code> otherwise.
|
||
|
* object matches, and <i>ifnone</i> is callable, then it is called
|
||
|
* and its result is returned. If there are no matches, and
|
||
|
* <i>ifnone</i> is not callable, then <i>ifnone</i> is returned.
|
||
|
* Returns <code>nil</code> otherwise.
|
||
|
*
|
||
|
* If no block is given, an enumerator is returned instead.
