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.

Structure

Sample Code

DummyDeployer.java

   private JavaEEComponentInformer informer;

   @Override
   public void deploy(DeploymentUnit unit, DummyMetaData deployment) throws DeploymentException
   {
      String appName = informer.getApplicationName(unit);
      String moduleName = informer.getModulePath(unit);
      String componentName = informer.getComponentName(unit);
      // do your stuff
   }

   @Inject
   public void setJavaEEComponentInformer(JavaEEComponentInformer informer)
   {
      this.informer = informer;
   }
