Method Details
- groupByField
  
  public static Map<String,List<UploadedFile>> groupByField(List<UploadedFilePart> parts, Map<String,FileSubmissionIndex.FieldFileEntry> fileIdIndex)
  
  Joins a flat list of UploadedFileParts with a FileId -> FieldFileEntry index (typically built by FileSubmissionIndex) and produces a field-keyed map of UploadedFiles. Each part's owning field and user-facing display name are looked up by the part's FileId.
  Parts with no matching index entry are dropped with a warn log — this can happen if a client uploads a binary whose id isn't referenced in the submission JSON. The returned files own their underlying deferred content; the caller is responsible for closing them via closeAll(Map) once they are no longer needed.
- closeAll
  
  public static void closeAll(@Nullable Map<String,List<UploadedFile>> files)
  
  Closes every UploadedFile in the supplied field-keyed map. Tolerant of nulls.
