Explain The Concept Of Lazy Data Access? |
|
Answer» The Web Dynpro FRAMEWORK has been built to follow the principle of Lazy Data Access. This means that the processing required to generate data will not be invoked until the data is actually needed. When this principle is APPLIED to the architecture of the context, it means that UNLESS there is an attempt to access the data in a singleton child node, then even though the lead selection in the PARENT node has changed, the child node’s supply function will not be called.
