Web Dynpro ParameterMapping API -
IWDParameterMapping
Overview
The parameter mapping is an instance of the UI element event. Therefore, it is defined at UI element level. You describe the parameter mapping for a UI element event using the wdDoModifyView method (see also Event Parameter and Parameter Mapping).
Since the parameter mapping is defined at UI element event level, each UI element event has a corresponding mapping information. Therefore, each UI element that can trigger events returns the mappingOf<UIElementEventName> method. This method returns an instance of the IWDParameterMapping interface. A button UI element with the onAction event provides the mappingOfOnAction that returns the current parameter mapping for the button instance.

Short Description |
|
Method name: addSourceMapping API: IWDParameterMapping |
(java.lang.String SourceName, java.lang.String NewName) |
void |
Adds a new parameter to the mapping list. The parameter is a constant value. It is read from the mapping source and stored in the IWDParameterMapping instance. The mapping source for actions is the number of UI element event parameters of a specific event. SourceName is the name of the parameter in the mapping source object. NewName is the parameter name after the mapping. |

Method name: addParameter API: IWDParameters |
(String name, String value) |
void |
Adds a new value to the parameter list. Name is the name of the parameter in the object. Value is the name of a constant value used as a parameter. |
