Class SavedAnnotationsHandler

java.lang.Object

ch.jalu.injector.handlers.dependency.SavedAnnotationsHandler

All Implemented Interfaces:

Handler

public class SavedAnnotationsHandler
extends Object
implements Handler

Simple handler that allows you to save a value for a custom annotation. Use this if you have a handful of custom values you want to be able to use as dependency. Create custom annotations to identify them by and register them before using the injector.

Don't forget that annotations need to have their retention set to runtime in order to be visible.
