Populate a variable set and all children using two REST calls to the Colectica Respotiroy

populateset.cs

// First, start with an instance of the variable scheme

var variableScheme = client.GetItem(variableSchemeId, ChildReferenceProcessing.Instantiate);

// The SetPopulator uses only two Repository calls to populate the entire item graph.
// The populator will call the Repository GetSet to find all identifiers, then the GetItems to retrieve all DDI for all items  
// It will recurse all the children, children of children, etc within this graph of items, and populate them

SetPopulator setPopulator = new SetPopulator(client);
variableScheme.Accept(setPopulator);

// The variable set, and all its children, are now completely populated.
