ATG 11.3 JAX-RS API – DropletInvoker

The DropletInvoker is used to invoke droplets and returns output data for each oparam. The droplet result gets filled up for each output of oparam using the call back mechanism.

•  Droplet Invoker object can be created using the constructor as below

              DropletInvoker dropletInvoker = new  DropletInvoker(“path to your droplet”);

             

•  Adding inputs to the invoker [addInput(String pKey, Object pObject)]

               dropletInvoker.addInput("pParamName1", pParamVal1);

               dropletInvoker.addInput("pParamName2", pParamVal2);

               dropletInvoker.addInput("pParamName3", pParamVal3);

•  Adding open parameter to the invoker

               OParam oParamOutput = dropletInvoker.addOParam("output");

• Adding output parameter to the invoker

              oParamOutput.addOutput("outputObj", " outputObj ");

•  Executing the droplet

             dropletInvoker.invoke();

• Getting the response from the execution

             OParam oParamOutputResponse = dropletInvoker.getOParam("output");

           if(oParamOutputResponse!=null){

                                Object responseObj = oParamOutputResponse.getOutput("outputObj ");

                                  …

                     }

Example code to invoke droplet to get the user details based on email id.

@GET

       ...

       public RepresentationModel getUser(@QueryParam("email") String email,@QueryParam("token") String authtoken) throws RestException {

              ...

              RepresentationModel.Builder builder = null;

              //Adds Input and output parameter to RestProfileDisplayWarningsDroplet

              DropletInvoker dropletInvoker = new  DropletInvoker("/com/../YourUserLookupDroplet");

              dropletInvoker.addInput("token", token);

              dropletInvoker.addInput("email", email);

              OParam oParamOutput = dropletInvoker.addOParam("output");

              oParamOutput.addOutput("users", "users");

              dropletInvoker.invoke();

              OParam oParamOutputResponse = dropletInvoker.getOParam("output");

              List usersRepItem = null;

              ResponsePayload responsePayload = getResponsePayload(); //Your custom Response Payload

             

              if(oParamOutputResponse!=null){

                     Output users = oParamOutputResponse.getOutput("users");

                     usersRepItem = (List)users.getObject();

                     RepositoryItem userItem = (RepositoryItem)usersRepItem.get(0);

                     builder = getRepresentationModelProfileBuilder(responsePayload, userItem);

              }

               return builder.build();

  }
