This section guides you on how to use the Graphical rule option while mapping and also introduces the different components of this option.
Elements of Graphical Rule
The Mapping Expression area has a floating menu that contains two options for you to switch between the Graphical and Textual rule. You can drag this floating menu anywhere in the Mapping Expression area.
Graphical elements are components which are used to represent any source, destination, mapping function, or parameter elements visually in Mapping Expression area. The following types of annotations described type, behavior, and functioning of the graphical interface and their elements.
Inputs: This shows the number of inputs a mapping function or a target element can have. Also, you can drag a line from input element to this section to use that as input in this mapping function/target element.
Label: It tells the name of the element.
Element Type: This displays the type of element being used in the mapping rule. The following list explains the types of elements:
Element type | Description |
---|
f(x) | A mapping function, variable, custom method, key function, context variable, connection variable, etc. |
S | A source element |
D | A destination element |
T | An XSL Template |
VM | A Value Map |
C | A Constant value |
Context Menus: Context menus are used to perform below actions:
- Start connecting lines to map an element to another element(s).
- Remove an element/box from the graphical mapping workspace.
- More Menu will have below options
- Information about mapping element
- Remove incoming mappings from the elements
- Add selected graphical mapping element's syntax/expression as a local variable.
