GetSourceDocumentNodes Method
Overloads
GetSourceDocumentNodes(Guid, Guid, String) |
Gets source document nodes for the specified relative path and the specified source document folder and QlikView Distribution Service ID. |
GetSourceDocumentNodes(Guid, Guid, String)
Gets source document nodes for the specified relative path and the specified source document folder and QlikView Distribution Service ID.
Declaration
List<DocumentNode> GetSourceDocumentNodes(Guid qdsID, Guid folderID, string relativePath)
Parameters
Type | Name | Description |
---|---|---|
System.Guid | qdsID |
The QlikView Disitribution Service ID for which to retrieve source document nodes. |
System.Guid | folderID |
The source document folder ID for which to retrieve source document nodes. |
System.String | relativePath |
The relative path for which to retrieve source document nodes. |
Returns
Type | Description |
---|---|
System.Collections.Generic.List<DocumentNode> |
Source document nodes for the specified relative path and the specified source document folder and QlikView Distribution Service ID. |
Remarks
This method is typically used to retrieve the source documents as a tree structure. Each returned DocumentNode contains a RelativePath property which describes where in the tree structure the node belongs. It also contains a IsSubFolder property that indicates whether the node represents a sub folder or a document.
To retrieve the first level of nodes under the source document root folder specified by folderID
,
set the relativePath
parameter to an empty string. For deeper levels of nodes, set the
relativePath
parameter to a path combined of the relative path and the name of the parent node at the previous
level.
The first level of nodes under each source document root folder will always contain a sub folder named <Orphans> that contains a folder structure of "ghost" source documents. Any such "ghost" source documents have at least one task assigned to it, but the document itself does no longer exist. Such "ghost" source documents will automatically disappear from the orphans structure when its tasks are removed or when the source document exist again. The source document node representing the orphans sub folder and all its sub nodes will have the IsOrphan property set to true.
security
Requires membership of local group QlikView Management API and the role Document Folder Administrator.
Examples
The following code example uses the QMS API to retrieve a registered QlikView Distribution Service, all its source document folders and nodes. The GetSourceDocumentNodes(Guid, Guid, String) method is called recursively to print sub folders and source documents as a tree structure. If anything goes wrong, it prints an error message.
The service key injection is assumed to be handled behind the scenes. For an example of how to inject the service key, see Samples.
