Creating a Mapping by using Visual Mapper
Object Services includes a visual designer that lets you add, modify, and delete request and response mappings of any of your Object Services by using a drag-and-drop interface.
The back-end object, data model, and the other objects and functions associated with the service are each displayed in their own container. Each container has one or more items listed within it. You can click on an item and drag your cursor to another item in another container to create new mappings.
Each mapping has a corresponding color associated with it.
- Gray corresponds to a valid mapping.
- Blue corresponds to a common mapping.
The design view is available along with a XML code view of your mappings. You can quickly switch between code view and the visual design view by clicking on the appropriate tab in the viewing pane.
Note: This video will walk you through understanding the Visual Mapper in your application: https://youtu.be/5JH9s3Qzx5g
The procedures in this section describe how to use the visual designer to manage your Object Service mappings.
How to View and Edit Mappings
You can examine any Object Service in visual design view that has request and response mappings. This section describes how to access visual design view for your services.
Note: The default visual design view pane is view-only and cannot be edited.
You can also edit your mappings by clicking the Edit button at the bottom of the viewing pane.
To access visual design view for a specific object service, do the following:
- In the Object Services list, click the ... button on the right side of the service listing you want to view, and then click Edit Configuration.
- In the navigation pane, click the Mapping tab.
- In the Mapping tab, click the item you want to view.
- Click either the Request Mapping or the Response Mapping tab.
- Under Request Mapping or Response Mapping, click the design view tab, which is located next to the Sample Mapping button.
After you are in visual design view, you can increase and decrease the zoom level of the viewing pane by clicking the + and - buttons in the upper-right corner of the pane. In addition, you can hide mappings by clicking the button below the zoom buttons and selecting which type of mappings you want to hide.
- If you want to edit your mappings for this service, click the Edit button in the lower-right corner of the page.
How to Add Mappings
You can map objects to each other by using your mouse to click on one item and then dragging to another item.
Depending on the type of item, the item can have multiple mappings from several different sources.
To map one item to another, do the following:
- Click and hold on the item you want to connect.
- While continuing to hold the mouse button, move your mouse cursor to the item you want to connect to and release the mouse button.
Note: If you attempt invalid mapping, an error message will appear.
How to Remove Mappings
You can remove all the existing mappings by clicking the Clear Mappings button.
If you want to remove individual mappings, select the mapping you want to remove, and press delete on your keyboard. You can select multiple mappings by holding down either
Ctrl keys and then selecting more mappings.
How-to Use Functions in the Visual Designer
When the visual designer is in Edit mode, the Toolbox pane lists built-in functions on the left side of the view.
The list includes all built-in mapper functions, as well as any custom functions you have created.
You can add new functions to your service by dragging and dropping the function from the list. You can also add, edit, import, export, and delete any custom functions you have.
To add a built-in function, do the following:
- Select the function you want to use from the function list.
- Click and hold the mouse button on the function.
- While continuing to hold the mouse button, move your mouse cursor to the location you want to place the function and release the mouse button.
