I’m using `OpenCSV` and it reads line-by-line of a CSV file via a `csvObject.readMap()`. I want to go through and collect each line into a `ArrayList`. `readMap` is done when it hits a null (empty line). What’s the best way to repeatedly call `readMap` and then put the result in an array?

```
do {
    val line = csv.readMap()
    csvLines.add(line)
} while (line != null)
```

this works but then the list has a null in it. i’d rather not have to do _two_ null checks if possible.
