When you add an application through the DE PMC, you must use the Add Application wizard. This wizard defines a consumer location to associate with your application, deploys your service package, and registers your application. After completing the steps with the wizard, your application should be ready to use.
Symphony calls onInvoke() on the service container once per task. This is where the calculation is performed.
To gain access to the data set from the client, you call the getTaskInput() method on the taskContext. The middleware is responsible for placing the input into the taskContext object.
The task context contains all information and functionality that is available to the service during an onInvoke() call in relation to the task that is being processed.
