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.
