Class JadConfig

java.lang.Object

com.github.joschi.jadconfig.JadConfig

public class JadConfig
extends Object

The main class for JadConfig. It's responsible for parsing the configuration bean(s) that contain(s) the annotated fields, use a Repository to read the raw configuration and assign the fields with the correct values.

The configuration bean(s) you pass in the constructor are expected to have one or more Parameter annotations on them.

You can pass either a single configuration bean or an array of objects. In the case of an array JadConfig will collect the Parameter annotations from all the objects passed in.
