Description

build a type representing a single configuration defined by a set of flags

The semi-automatic assembly of processing node invocation code utilises some metaprogramming to generate a factory, which in turn produces node wiring objects according to the configuration to be used for the corresponding ProcNode. This relies on generating a distinct type based on a given set of configuration flags, which is covered by this test.
