Difference between Delegated Node and BO Representation Node

[Former Member]

Hello Fellow BOPFers,

Firstly I would like to thank you all for the helpful blogs and posts in this space; it really helped a lot.

I have recently started to get my hands dirty on BOPF. I have created a demo BO with a delegated node TEXT_COLLECTION and BO representation node CHANGE_DOCUMENT. TEXT_COLLECTION is populated by the consumer API whereas CHANGE_DOCUMENT is populated by the framework. I was wondering if there was any other difference between these 2 node types other than the manner in which they are populated.

Thanks

Hello Kiran,

a "delegated node" represents an included Dependent Object (e.g. TEXT_COLLECTION) in its host Business Object. At runtime, it is replaced by the nodes of the DO.

A "representation node" represents a foreign Business Object (not a Dependent Object) in order to allow you to navigate to that foreign BO via retrieve-by-associations. So it is not an inclusion (like in the "delegated node" case) but only a kind of a reference.

Best regards

Thank you for your response David.

I noticed the upon generating the BO, the framework generates associations for both TEXT_COLLECTION and CHANGE_DOCUMENT.

I tested my demo BO using BOPT to create entries for ROOT and TEXT_COLLECTION. Change document were created automatically by the framework. WOW:-)

I havent got around to reading the entries but am assuming that I will have to use READ_BY_ASSOCIATION for both nodes, TEXT_COLLECTION and CHANGE_DOCUMENT.

Please correct me if my understanding is incorrect.

Thanks!
