Package com.sap.tc.webdynpro.progmodel.api Description

Contains interfaces and classes that form the core programming model for Web Dynpro applications. Instances of these interfaces are provided to the application where needed, so no factories exist for most of them.

Application dependent Subinterfaces

For applications that are build with the Web Dynpro development workbench, typed subinterfaces of IWDController, IWDContext, IWDNode and IWDNodeElement will be generated were appropriate. Thereby the need to cast from a generic type (as java.lang.Object) to a more concrete, application dependent one (like com.sap.BusinessPartner), is reduced. Nevertheless can application developers use the generic functionality as well.

Dynamically Modifiying the Context Structure at Runtime

The context of a controller normally gets declared at design time and a generated typed version is used at runtime. But in those cases where the context structure needed for a controller is not or not fully known at design time, it can be defined/modified at runtime. Therefore the structure information declared at design time is provided at runtime as well (see IWDContext.getRootNodeInfo(), IWDNode.getNodeInfo(), IWDNodeInfo and IWDAttributeInfo). It can be enriched at runtime by adding nodes or attributes as needed. After modifiying the structure information, the added context elements can then be accessed with the generic access methods IWDNode.getChildNode(String,int), IWDNodeElement.getAttributeValue(String) and IWDNodeElement.setAttributeValue(String,Object)
