Is there a OOTB functionality to empty the contents of KC or to get all the top

Some useful plug-ins you can combine to meet your requirement or use as examples to build your own:


Content Functions

Empty Folder

Thanks eduardo but I have already gone through these functions and didn't find one such that satisfies the requirement. Could you please let me know if I am missing any thing here?

1. You can use the Content Functions as an example to create your own custom function plug-in to retrieve all folders from a KC. Here's an example:

@Function
@FolderDataType
public Long[] GetAllFoldersFromKC(ServiceContext sc, ContentService cs, @Parameter(required=true) @KnowledgeCenterDataType Long knowledgeCenter) {
ContentFilter cf = new ContentFilter(ContentConstants.TYPE_FOLDER);
return cs.getAllChildrenIds(knowledgeCenter, cf, ContentConstants.GC_MOD_NORMAL);
}


2. Then you can pass the result of calling this function to the Empty Folder smart service available in the second plug-in from my post

3. You can now use the Delete Folder smart service to delete the empty folders that function #1 will return.

Or you can merge these three things in your own custom smart service called "Empty KC"

@Eduardo I have created a smart service as per your suggestion #3. But I do have a question - as of now the smart service has a input called 'knowledgeCenterId' which is of type Number Integer. In the smart service how can I check if a knowledge center exists or not with the input received from smart service? Because if I doesn't make this check, the smart service is fetching the child contents of the object (irrespective of KC or folder) based on the id and deleting them.

I know that I could do it with KnowledgeCenter data type but I would like to prefer to do it with the knowledgeCenterId which is of type Number. Is there any mistake in this approach?

It would be grateful to hear back from you.

Once you have the retrieved the Content object based on the ID do something like this:

if (content.getType().equals(ContentConstants.TYPE_COMMUNITY_KC)){
......

}

@Eduardo Many thanks. Unfortunately I didn't find getType() initially.
