The DataSetFolderType ObjectType is a concrete type and can be used directly.
Instances of the DataSetFolderType can contain PublishedDataSets or other instances of the DataSetFolderType. This can be used to build a tree of Folder Objects used to group the configured PublishedDataSets.
The PublishedDataSetType Objects are added as components to the instance of the DataSetFolderType. An instance of a PublishedDataSetType is referenced only from one DataSetFolder. If the DataSetFolder is deleted, all referenced PublishedDataSetType Objects are deleted with the folder.
PublishedDataSetType Objects may be configured with product specific configuration tools or added and removed through the Methods AddPublishedDataItems, AddPublishedEvents and RemovePublishedDataSet. The PublishedDataSetType is defined in 9.1.4.2.1.
This Method is used to create a PublishedDataSets Object of type PublishedDataItemsType and to add it to the DataSetFolderType Object. The configuration parameters passed in with this Method are further described in the PublishedDataItemsType defined in 9.1.4.3.1 and the PublishedDataSetType defined in 9.1.4.2.
The settings in the VariablesToAdd are used to configure the data acquisition for the DataSet and are used to initialize the PublishedData Property of the PublishedDataItemsType.
The DataSetMetaData of the PublishedDataSetType is created from meta-data of the Variables referenced in VariablesToAdd and the settings in FieldNameAliases and FieldFlags.
The Client shall be authorized to modify the configuration for the PubSub functionality when invoking this Method on the Server.
