# mdlCodeMaps

`mdlCodeMaps` is a shared VB.NET Module that exposes the `ExternalViewTypes` extended code map used by the imaging library to map external view type values to their descriptions or identifiers.

## Purpose
- Provides a shared code map for external view types, accessible without instantiation (as a VB.NET Module)*.

## Context
- Namespace: `SAIF.Business.Imaging`
- Assembly/package: `SAIF.BOF.Business.Imaging`

## Public members

| Member | Signature | Purpose |
| --- | --- | --- |
| `GetImageExternalViewCodes` | `Public Function GetImageExternalViewCodes(dpi As IDataPortalInfo, Optional ByVal inRefresh As Boolean = False) As clsExternalCodesMap` | Returns the cached external-view code map, optionally rebuilding it when `inRefresh=True`. |
| `clsExternalCodesMap` | `Public Class clsExternalCodesMap` | Nested map type that loads `image_external_view_code` rows into an extended code map keyed by code and enum value. |
| `ExternalViewTypes` | `Public Enum ExternalViewTypes` | Enumerates the supported external-view states: `Hide`, `Show`, and `Pending`. |

## Behavioral notes
- As a VB.NET Module, all members are implicitly shared and accessed without instantiation*.
- No database interaction was identified for this module.

## Constraints and usage notes
- `GetImageExternalViewCodes` caches the module-level map in a `Static` variable until a caller requests a refresh.
