Class PackageGenerator

java.lang.Object

de.tsl2.nano.util.codegen.ClassGenerator

de.tsl2.nano.util.codegen.PackageGenerator

public class PackageGenerator
extends ClassGenerator

 This class is only used manually to recreate the default presenters.
 It is able to load model classes from a given path or a given jar-file.
 
 If you use a jar-file, be sure to set the classpath to find all needed classes!
 
 how-to-start: start the main of this class with parameter:
   1. package path to find model classes to generate presenters for
   2. class name of presenter specialization
   3. property-file name
   
 example:
  PackageGenerator bin/org/anonymous/project/ de.tsl2.nano.codegen.PresenterGenerator
  PackageGenerator lib/mymodel.jar de.tsl2.nano.codegen.PresenterGenerator
  
 To constrain the generation to a specific package path, set the environment variable "bean.generation.packagename".
