| * @assertion bool contains(Object element) |
| * Returns true if the collection contains an element equal to element. |
| * This operation will check each element in order for being equal to element, |
| * unless it has a more efficient way to find an element equal to element. |
| * The equality used to determine whether element is equal to an element of the |
| * iterable defaults to the Object.== of the element. |
| * @description Checks that true is returned if there is an element in this list |
| * equal to element, false otherwise. |
