Refactor abstract form generation: make it functional #170

Open jmvanel opened 7 years ago

jmvanel commented 7 years ago

In english

A follow-p of #169 The steps must be good algorithms in functional programming. That is to say a sequence of pure functions, one per sub-step:

EmptyInitialState.step1.step2

Concerned steps

Abstract form generation
- label
- compute Properties List
- OWL/RDFS inferences
- Range Inference
- Thumbnail Inference
- ...
HTML generation
- label
- display: literal, resource and BN triples
- edition: literal, resource and BN triples

Refactorings

RawDataForForm and FormSyntax should be identical
each step will have signature def step(formSyntax: FormSyntax): FormSyntax
main function to modularize; FormSyntaxFactory.createFormDetailed2()

En français

Il faut que les étapes soit des bons algorithmes en programmation fonctionnelle. C'est à dire un enchaînement de fonctions pures, une par sous étape:

EtatInitialVide.etape1.etape2

See the TODO's in code:

grep TODO abstract_syntax/src/main/scala/deductions/runtime/abstract_syntax/FormSyntaxFactory.scala

An idea is to use function chaining in Scala:

val pipeline = Function.chain(Seq( func1, func2 ))
pipeline(initFormSyntax)
// or
(func1 andThen func2)(initFormSyntax)
