hey, I have a repository that returns a nullable object, how do i make a nice code that returns a field of that object if the object exists and otherwise does some other business?

you could make use of an extension funktion with nullable receiver

i ended up with something like this:

```
fun getConfigByAgentName(agentName: String): String {
        var agentConfig = configRepository.findByName(agentName)?.configText
        if (agentConfig != null) {
            return agentConfig
        }
        agentConfig = computeConfig(agentName)
        configRepository.save(Config(name = agentName, addedAt = LocalDateTime.now(), configText = agentConfig))
        return agentConfig
    }
```

Is repository some Android thing? `return repo.getByNamr(agentName) ?: loadDefaultByName(agentName)`

Note that the loadDefaultByName fun could be defined in the getConfigByAgentName method itself if needed
