Detailed Description
template<typename ReturnType>
class VCF::DelegateR< ReturnType >
The base calss for delegates that return a value from a function.
This delegate returns a value of type ReturnType but has no arguments.
The delegate stores all the return values in a vector of type ReturnType. You can access the values via the results member variable which is marked as public.
When the invoke() method returns the results vector will have been populated with all the return values from the callbacks, stored in the order the callbacks were called in. The return result for invoke() is the return value of the last callback.
If the delegate is invoked asynchronously with beingInvoke() then if you want to get the return value(s) you need ot call either endInvoke(), or endInvokeWithResults() to get all the return values.

Gets the result for the AsyncResult instance that was returned by the previous call to beginInvoke().
- Returns:
- ReturnType returns the return value of the last callback.

Gets the results for the AsyncResult instance that was returned by the previous call to beginInvoke().
- Returns:
- Results returns an a array of results, reprepresenting all the return values for each callback that was called. The collection is a vector of ReturnType.
