Subsystem spiralcraft.command

Module: spiralcraft-core

Provides a Command pattern that exposes arbitrary functions on application components to user interface or other controllers designed to trigger application functions generically.

Example:

package myPackage;

import spiralcraft.command.Command;
import spiralcraft.command.CommandAdapter;

public class MyWidget
{  
  public String doWork(String x,int y)
  {
  }
  
  public Command<MyWidget,String> doWorkCommand(final String x,final int y)
  {
    return new CommandAdapter<MyClass,Void>()
    {
      setTarget(MyWidget.this);
      @Override
      protected void run()
      { 
        try
        { setResult(doWork(x,y));
        }
        catch (Exception ex)
        { setException(ex);
        }
      }
    };
  }
  
}
