Custom Processes Ocean provides the WorkstepProcessWrapper convenience class to make this easy. It creates a Process from your Workstep. WorkstepProcessWrapper custom Workstep Fig. 6-62 Workstep Wrapped to Become a Process There are four steps to create a process from an existing workstep. 1 Create a process from your workstep using WorkstepProcessWrapper. 2 When you have a custom UI, enhance the UI behavior. 3 Implement persistence on the workstep argument package. 4 Add your process to the Petrel Process diagram. Step 1 - Create Process via WorkstepProcess-Wrapper The Ocean class WorkstepProcessWrapper creates a process from your workstep. public class WorkstepProcessWrapper : Process { public WorkstepProcessWrapper(Workstep workstep); public object ArgumentPackage { get; } public Workstep Workstep { get; } protected override Control CreateUICore(); } public sealed class Context : WorkflowContext { ... } Pass an instance of the workstep to the wrapper class constructor. MyUpscalingWorkstep w = new MyUpscalingWorkstep(); Process p = new WorkstepProcessWrapper(w); 6-340 Ocean Application Development Framework 2008.1 Schlumberger Private
Custom Processes The wrapper re-uses the definitions and information from the given Workstep to build a process: • An instance of the workstep argument package is used for state persistence of the process. • The workstep's UI is used for the Process settings dialog. The process UI will use whatever UI is provided for the workstep. It can be the default UI generated by Ocean or a custom UI you created. Using the Ocean-generated UI makes things easy. Ocean will transfer the data between your workstep’s argument package and the default UI automatically. Ocean takes the values the user enters into the UI and loads them into the argument package before the process runs. When the process is finished, Ocean pulls the output arguments from the argument package and populates the UI with them so the end user can see the results. Step 2 - Custom UI: Change UI Behavior If you have provided a custom UI, Ocean will not be able to connect your argument package to your custom UI. You will have to write the code to transfer the data between the UI and the argument package. This will be done when the user clicks on your Apply or OK buttons. Now your custom UI is going to be called from two different environments: from the Workflow editor and from the Process diagram. The behavior of your UI is different in each instance. As we saw previously, when your UI is called from the Workflow editor, the Apply button will update the argument package and call the argument package changed method. When your UI is called from the Process diagram, the behavior is different. The Apply button will still update the argument package, but then it needs to actually invoke the workstep behind it and then update the UI to display any output values.
