[opencms-dev] I_CmsModuleAction

[ruben malchow]

hello andy, ...

the core of opencms is a singleton, and thus it is only instantiated 
once, and it only creates one instance of the module class, too. it also 
holds a reference to the module action object, so it will not disappear.

a.) to store the reference to CmsObject that is being passed to the 
initialize() method, you could do something like this:

      
    public class BlahAction extends A_CmsModuleAction {
      
        private CmsObject co;

        [...]

        public void initialize(
            CmsObject _co,
            CmsConfigurationManager _ccm,
            CmsModule _cm) {
           this.co = _co;
        }
    }

b.) to get a reference to the module's instance, you could simply do 
something like this:

    public class BlahAction extends A_CmsModuleAction {
      
        private static BlahAction instance;

        public void initialize(...) {
            instance=this; 
        }
      
        public static BlahAction getBlahAction() {
            return instance; 
        }
    }
  
you will have to check the return value of getBlahAction, though. if the 
modules hasn't been initialized properly, it will be null.

this concludes our lesson for today. in the next session, we will try to 
combine a.) and b.) ...
