DAPI

Hi
I've used these functions:

DAPI.GetNode(nameSorgente, wfFolderDaScanner)
DAPI.ListSubNodes(wfFolderSorgente)
DAPI.GetNodeByID(dSession, NodeID_DaScanner)

Do you think that they will give me problem?

Thanks in advance

I think this has bearing on what I posted some time back as in do not use DAPI ,However that was not my intention.For this you need to understand the evolution of LL software now called CS.When the version 8.+ was prevalent and I saw it,it had a different model and one would freely use the DAPI Package.Later when 9.0 was introduced I remember OT telling us about using LLIAPI. If you think it is almost an approximation of making OScript look like other OOP languages .People like Chris Meyer has already taken the language to almost a new level and I do not know much about Computer science nerdy stuff but OScript is not a OOP language but several pundits rate it better than OOP languages.So what I am saying is pay close attention to what OT Programmers are doing.Do you see them use DAPI.LIstNodes in their Requesthandlers probably they are using LLIAPI::LLNode::NodeListContents

That Ospace is where I look first for things I may need to perform.

If you look at that you will see DAPI.ListContents but then they gracefully allow callbacks(insertion or interruption of other module's requirements).This is the reason why I and a lot of others who have been exposed to this says to use that.So a good clue is to debug a Livelink call and see how OT code is getting called.The hack/kludgy solutions that one puts out in just to get something done and earn a paycheck sometimes will come to haunt you.So when possible take a class room approach or look at code.OT's may be the most open source even better than opensource.It is written for you to see and use accordingly.Before I posted my reply I quickly tested the DAPI.GetNode call the code is also attached in case somebody needs a better hint.

That is my approach,pay special attention to things that extremely popular OT programmers/architects say (David Templeton,Kyle Swidrowich, Hans Stoop and a whole lot of others ) over the years I read upon their advises and try to write code using that.

Hope some of it made sense and can be adopted/adapted...

//does that node exist in that path

Dynamic docNode = DAPI.GetNode("APLNG - Request For Information (RFI):Reports",startNode,false)

echo(docNode.pname)

//a non existent node

docNode = DAPI.GetNode("APLNG - Request For Information (RFI):DOESNOTEXIST",startNode,false)

if isError(docNode)

Echo ("API ERROR ocurred "+Error.ErrorToString(docNode))

Just to add on to Appu's points, a very good reason to use an equivalent function in LLNode() rather than a DAPI function, is that more often than not, it includes permission checks. For example. DAPI.ListSubNodes() or DAPI.ListContents() will allow you to fetch all nodes, although both functions today allow you to pass in an optional Perm mask. In this example, most of the time you would want all child nodes that a user has See + See Contents for, and nothing else.

In the same vein, using the DApi.AddVersion() to upload a version should be avoided like the plague! Always use LLNode().NodeAddVersion() as it also manages the transaction so you don't have to.

Thank you Appu and Hugh,
I was looking for clarification as well and still think is pretty awkward LLIAPI are not mentioned on SDK documentation.

Hi Roberto,

That is a good point. I was looking at earlier versions of the SDK documentation and the LLIAPI section was part of it. We will investigate internally to understand why it was removed from the documentation.

Thanks for pointing this out!

Hi Roberto,

In CS 10.0 U 2016-06 at least, it can be found under Index:Livelink Module Index : Kernel : LLIAPI : LLNode.

I can't test CS 16 from work because my client's corporate IT policy for servers is that they can only be accessed from accounts with Internet access disabled. My feature request for OpenText is to allow some sort of off-line documentation option for licenced users with this scenario. It is fairly common across the Government of Canada.

Hi Hugh,

This was discussed before and Open Text delivers the documentation also in an offline format:
