# OnlineMessagesMappingHelper

A static helper that registers the AutoMapper class maps needed to project `OnlineMessages` data-model rows (and their priority/user-type codes) into the `OnlineMessage`/`CodeDescription` contracts, in either English or Spanish-preferring form. It has no injected collaborators and holds no instance state; it configures the process-wide static `Mapper`.

## Purpose
- Registers the English-language mapping from `OnlineMessages` to `OnlineMessage`, using the message's native text/title fields.
- Registers the Spanish-preferring mapping from `OnlineMessages` to `OnlineMessage`, falling back to the English text/title when the Spanish fields are blank.
- Registers the shared priority-code and user-type-code to `CodeDescription` mappings used by both language variants.

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

## Public members
This type declares no public members; both `CreateOnlineEnMessageMappings` and `CreateOnlineEsMessageMappings` are `internal static` methods, callable only from within the `SAIF.Services` assembly.

## Behavioral notes
- Although the class itself is declared `public`, none of its members are accessible outside the `SAIF.Services` assembly, so it functions as an assembly-internal AutoMapper configuration helper rather than a consumable public API*.
- Both mapping methods re-register the priority-code and user-type-code maps, so calling both in the same process registers those two maps twice; AutoMapper's static `Mapper.CreateMap` calls are typically idempotent for identical map definitions*.
