LoaderSettings

Loader settings cover all options related explicitly (only) to file loading.

Creating a builder

Settings introduced by BoostedYAML follow builder design pattern, e.g. you may build your own settings using:

LoaderSettings.builder() /*configure*/ .build()

Basic settings

Create file if absent

Builder#setCreateFileIfAbsent(boolean createFileIfAbsent)

Sets if to create a new file and save it if it does not exist automatically.

Not effective if there is no file associated with the document.

Default: true (enabled)

Update automatically

Builder#setAutoUpdate(boolean autoUpdate)

If enabled, automatically calls YamlFile#update() after the document has been loaded.

Not effective if there are no defaults associated with the document.

Default: false (disabled)
