# EdiFileService

Persists and deletes parsed EDI file structures via `IUnitOfWork`, translating an in-memory `IEdiFile` (segments, data elements, and composite data elements) into the `SAIF.Data.Model.Edi.EdiFile`/`EdiSegment`/`EdiDataElement` persistence model.

## Purpose
- Converts a parsed `IEdiFile` (segments/elements/composite elements) into the EDI data-model entity graph and saves it in one transaction.
- Deletes a previously stored EDI file by its identifier.

## Context
- Namespace: `SAIF.Services.Utilities.Edi`
- Assembly/package: `SAIF.Services` (packaged inside the `SAIF.SAIFCode.Core` NuGet package)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| EdiFileService(...) | `public EdiFileService(IUnitOfWork uow)` | Stores the unit of work used for all EDI file persistence, after verifying it is not null. |
| LoadFile | `public void LoadFile(IEdiFile file, string description)` | Builds an `EdiFile` entity (with a `description` and current timestamp) from `file`'s segments/data elements/composite elements — including nested composite child elements — and commits it to the repository in one transaction. |
| DeleteFile | `public void DeleteFile(long fileId)` | Loads the `EdiFile` entity with `fileId` and deletes it within a transaction if found; otherwise does nothing. |

## Behavioral notes
- `LoadFile` wraps the entire entity-graph build and insert in a single `unitOfWork.Begin()`/`Commit()` transaction.
- Composite data elements (`IEdiCompositeDataElement`) are expanded into individual child `EdiDataElement` rows tagged with `CompositeIndex`, in addition to the composite element itself being added to the segment.
