public ListInterface::set($index, $value)
Sets the value of the item at a given position in the list.
Parameters
int $index: The position of the item in the list. Since a List only contains sequential, 0-based indexes, $index has to be:
- Either the position of an existing item in the list. This updates the
item value.
- Or the next available position in the sequence of the current list
indexes. This appends a new item with the provided value at the end of the list.
mixed $value: The value of the item to be stored at the specified position.
Return value
$this
Throws
\InvalidArgumentException If the $index is invalid (non-numeric, or pointing to an invalid position in the list).
\Drupal\Core\TypedData\Exception\MissingDataException If the complex data structure is unset and no item can be set.
