Interface Declaration Builders create vertex interfaces from a template parameter pack. This allows developers to express their node interfaces as declarations as opposed to requiring them to sequentially construct their interfaces.

For example, we can do:

FInputVertexInterface Interface { TInputDataVertex(...), FBeginSubInterface(...), TInputDataVertex(...), FEndSubInterface(...), TInputDataVertex(...) };

As opposed to: FInputVertexInterface Interface;

Interface.Add(TInputDataVertex(...)); Interface.Add(FBeginSubInterface(...)); Interface.Add(TInputDataVertex(...)); Interface.Add(FEndSubInterface(...)); Interface.Add(TInputDataVertex(...);

An essential element of the builders is that they use member function overloading of Add(...) to handle the variety of different objects which might be used to describe an interface.

The builders also size memory allocations exactly to remove any addition slack. In general, there can be many interfaces in memory and minimizing their memory footprint is important. Base class for an interface builder which supports sub interfaces.
