(->field-selection {:keys [selection positions] :as spec})

Same a field-selection but also behave as identity when input is already a FieldSelection object

->writable clj

(->writable input)

field-selection clj

(field-selection {:keys [type-hint schema]})

(field-selection type-hint schema)

Builds a FieldSelection object from a Clojure schema. Three formats are allowed and must be hinted :

• map representation : {:a {:b {:d false , :e 1.0} :f 'koala'}}, there keys are default values (only numbers, text and boolean are supported for now, nil meaning no default value)
• regular representation : DL4J input format [[:a :b :d] [:a :b :e] [:a :f]] The statements above might evolve in more mature iterations
