MapBackedSource

abstract class MapBackedSource(entries: Map<String, String>, origin: String? = null) : ConfigSource(source)

Base ConfigSource backed by an in-memory map with case-insensitive fallback lookup. origin, such as a file path, is added to name so reports tell sources of one type apart: TomlSource(config/app.dev.toml).

Constructors

MapBackedSource

constructor(entries: Map<String, String>, origin: String? = null)

Properties

fallbackKeyFormats

open val fallbackKeyFormats: List<KeyFormat>

Further formats tried in order when the key in keyFormat has no value. None by default.

keyFormat

abstract val keyFormat: KeyFormat

The key format tried first, e.g. KeyFormat.SCREAMING_SNAKE for environment variables.

name

open override val name: String

A short label for reports such as ConfigLoader.explain, e.g. TomlSource.

Functions

children

open override fun children(key: String): Map<String, String>?

Entries nested under key as key.child, keyed by child, or null if there are none. Sources that flatten tables and mappings (TOML, YAML, properties) use this to fill Map fields.

get

open override fun get(key: String): String?

The raw text for key, or null if this source does not have it.
