VDF Informer

Version 1

    Context

    A deployer needs to act upon information stored within a deployment unit.

    Problem

    The deployer is unaware of the mechanism to extract such information from the deployment unit.

    Solution

    The deployer delegates to an informer to let the informer provide the information for the deployment to happen.

       {
          String appName = informer.getApplicationName(unit);
          String moduleName = informer.getModulePath(unit);
          String componentName = informer.getComponentName(unit);
          // do your stuff
       }
