IWDNode and IWDNodeInfo

Hi,

I am new to webdynpro.

Can anyone explain the purpose of IWDNode and IWDNodeInfo?

Where do we use it? Is it used only in dynamic programming to create the context and context attributes or does it serves any other purpose.

Regards

Hi

IWDNODE - Actual data

Node actually creates a structure and adds attributes to it which can store values.

IWDNODEINFO-Metadata(description of Data)

Nodeinfo gives the metadata information of the node like cardinality ,selection property etc.,

Hi,

I guess the basic difference is:

IWDNodeInfo - To design the context - To create attributes, child nodes etc..

IWDNode - To access the data in the node at runtime - To create the data elements, binding elements..etc..

One is the actual element reference and other is like its Meta data.

IWDNode is the actual element reference or i shall say the parent class of the node that you would create.

IWDNodeInfo is something like a metadata that contains its properties and attributes.

IWDNode, is not nacessarily used only in dynamic programming but you will find its use in regular WD work also.

IWDNodeInfo is used only in dynamic programming, where you might want to set/get the node properties.

I hope it helps.
