Examples of com.google.feedserver.util.BeanCliHelper

• com.google.feedserver.util.BeanCliHelper
  Uses reflection to scan registered beans for any annotation containing {@link Flag} or {@link ConfigFile}. It uses the "help" entry in the Flag decorator for flag help. In addition if you specify @ConfigFile with @Flag, this flag will be used to read an XML file from the filesystem containing a payload-in-content entry for this bean. It will read the file first then reads the flags. Flags supersede file content. With this class you can create configuration files using payload-in-content files and have them represented as Beans for consumption in code.

  
  Boolean, Integer and String fields are supported.
  example: to setup --filename as a flag. in class Foo with flag help.

   public class FooBean { {@literal @}Flag(help = "config file for foobean") {@literal @}ConfigFile  private String configFileName = "/etc/configfile"; {@literal @}Flag(help = "filename to access")  private String filename = "/tmp/defaultfile"; public getFilename() {  return filename;  } public setFilename(String filename) {  this.filename = filename;  } } public class Foo { public static void main(String[] args) {  FooBean fooBean = new FooBean();  BeanCliHelper cliHelper = new BeanCliHelper(); cliHelper.register(fooBean); cliHelper.parse(args); System.stdout.println("Filename is " + fooBean.getFilename());  }  } 

  Note: classes with identical flag field names will get overwritten with the last one processed. TODO(rayc) support collision detection and use fully qualified class name for flag option. @author r@kuci.org (Ray Colline)
