Class ReloadNotifierImpl<T>

java.lang.Object
ch.kk7.confij.pipeline.reload.ReloadNotifierImpl<T>
Type Parameters:
T -
All Implemented Interfaces:
ConfijReloadNotifier<T>
public class ReloadNotifierImpl<T>
extends java.lang.Object
implements ConfijReloadNotifier<T>
Keep track of previous configuration values and compares them to new ones (when the source value / config string changes). Will notify all listeners of the changed value. Given one nested value changes, the parent will also be notified of the change.

The class is internally thread-safe, but if a config is reloaded before all handlers are registered it will crash out.
