# DocumentOverrideService

Implements `IDocumentOverrideService` as a lookup for configured exceptions to the default document-classification rules: given an EDI document-type code and a provider-type code, it returns an alternate OnBase document type/subtype when a specific override has been configured for that combination, via `IEbillDocumentQueryProvider`.

## Purpose
- Resolves whether a document-type/provider-type combination has a configured OnBase classification override, returning `null` when no override applies (`CheckForOverride`).

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

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| DocumentOverrideService | `public DocumentOverrideService(IEbillDocumentQueryProvider queryProvider)` | Wires the e-bill document query provider used to look up configured classification overrides. |
| CheckForOverride | `public DocumentOverrideResult CheckForOverride(string ebillDocumentTypeCode, string providerTypeCode)` | Returns the overridden OnBase document type and subtype for the given EDI document-type/provider-type pair, or `null` if no override is configured. |

## Behavioral notes
- Consumed by `ConfigurationService.GetImageClassification` to replace the document's default classification only when an override record exists.
