insertAt ( index : Integer, object : T) : Sequence(T)
Returns a Sequence containing self with object inserted at the *index* position.
| Expression | Result |
|---|---|
| Sequence{'a', 'b'}->insertAt(0, 'c') | invalid |
| Sequence{'a', 'b'}->insertAt(1, 'c') | Sequence{'c', 'a', 'b'} |
| Sequence{'a', 'b'}->insertAt(3, 'c') | Sequence{'a', 'b', 'c'} |
| Sequence{'a', 'b'}->insertAt(4, 'c') | invalid |
Insert an object in a specific place in a collection or association. <collection>.insertAt(<position>, <object>)
Used when you don't want a new object at the end using add.
For associations, it only makes sense to use insertAt on ordered associations.
- Note that the position is 1-based, not 0.
