Class LoadList

java.lang.Object

asia.redact.bracket.properties.ref.LoadList

public class LoadList
extends Object

Container for list of references from which to load properties. The list can contain externalized files, internal files within the classpath (such as in a jar file) and even direct name value pairs.

The key idea is that if we load references in a given order, the properties values will be added and later additions will overwrite earlier ones. This means you can load a template file first (perhaps from the classpath) and then an override certain values from the file system afterwards.
