Description

I am writing a framework that builds a Twill app from a specification. While the builder pattern is convenient and foolproof for verbose construction of the app spec, it is cumbersome to use programmatically:

TwillSpecification.Builder.MoreRunnable builder =
TwillSpecification.Builder.with().setName(className).withRunnable();

// iterate over my spec and add runnables
TwillSpecification.Builder.RunnableSetter setter = null;
for (...)

{ ResourceSpecification resources = ... String name = ... TwillRunnable runnable = ... setter = setter == null ? builder.add(name, runnable, resources).noLocalFiles() : builder.add(name, runnable, resources).noLocalFiles(); }

}
// iterate over my spec and configure the order of runnables
TwillSpecification.Builder.NextOrder nextOrder = null;
for (...)

{ String runnableName = ... // my logic String[] runnableNames = ... // my logic nextOrder = nextOrder == null ? setter.withOrder().begin(runnableName, runnableNames) : nextOrder.nextWhenCompleted(runnableName, runnableNames); }

return nextOrder == null ? setter.anyOrder().build() : nextOrder.build();

If would be easier if I did not have to use the builder pattern...
