Class Atz_ClassLoader

java.lang.Object
  org.atzberger.application.selm_builder.Atz_ClassLoader

public class Atz_ClassLoader
extends java.lang.Object

Custom class loader allowing for retrieval of object instances for both the default classes implemented with this application and future extension classes supplied by users. The loader scans the class path associated with the build to find classes.

Automatic loading of objects of a generic type are also supported, such as loading all editor panels for a particular data type during initialization of the application.

The class loader allow for reflection features to be used in Java allowing for instantiation of new objects by providing a compiled class file and simply knowing the class name and constructor.
