# PaymentAndFacilityMatchRule

`PaymentAndFacilityMatchRule` is an `IProviderMatchRule` for billers that supplied both a payment and a facility address (with or without a physical address as well): when the payment and facility addresses textually match each other, it delegates to `PaymentOnlyMatchRule`; otherwise it independently matches the payment and facility addresses against two-address provider locations and requires both matches to intersect to the same unique location. It is the primary rule `ProviderIndexerV2` tries first for the wider (physical+payment+facility) rule chain ([DOM-BR-028](../../business-rules.md#dom-br-028-v2-indexing)).

## Purpose
- Applies when the biller has payment and facility addresses, or physical, payment, and facility addresses together.
- When the biller's payment and facility addresses match each other, reduces to the simpler single-address matching implemented by `PaymentOnlyMatchRule`.
- Otherwise independently matches the payment and facility addresses against two-address provider locations and requires the two matched-location sets to intersect to exactly one location.

## Context
- Namespace: `SAIF.Domain.Claims.Ebilling.Indexing`
- Assembly/package: `SAIF.Domain` (`Domain/SAIF.Domain/SAIF.Domain.csproj`, .NET Framework 4.6.2 class library)

## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| PaymentAndFacilityMatchRule (constructor) | `public PaymentAndFacilityMatchRule(IEnumerable<EbillAddress> ebillAddresses, IEnumerable<ProviderAddress> physicalAddresses)` | Initializes the rule with the biller's e-bill addresses and the candidate provider addresses, via `ProviderMatchBase`. |
| UniqueProviderLocationMatch | `public ProviderLocation UniqueProviderLocationMatch(bool concatenateTwoLineBillAddresses)` | Applies only when the biller has payment and facility addresses (with or without physical), then either delegates to `PaymentOnlyMatchRule` (when those addresses match) or intersects independent payment/facility matches, returning `null` when neither path finds a unique location. |

## Inherited public members

Members in this section are inherited from `ProviderMatchBase` in `SAIF.Domain`. They are available on this type through inheritance.

| Member | Signature | Purpose | Origin |
| --- | --- | --- | --- |
| BillerHasPhysicalPaymentAndFacilityAddresses | `public bool BillerHasPhysicalPaymentAndFacilityAddresses()` | Reports whether the biller has all three address roles present. | `SAIF.Domain` — `ProviderMatchBase` |
| EbillAddressAndProviderAddressMatch | `public static bool EbillAddressAndProviderAddressMatch(EbillAddress ebillAddress, ProviderAddress providerAddress, bool concatenateTwoLineBillAddresses)` | Reports whether an e-bill address matches a candidate provider address on Line1 (optionally concatenated with Line2), City, and zero-padded zip code ([DOM-BR-022](../../business-rules.md#dom-br-022-address-match)). | `SAIF.Domain` — `ProviderMatchBase` |
| TwoEbillAddressesMatch | `public static bool TwoEbillAddressesMatch(EbillAddress addressOne, EbillAddress addressTwo)` | Reports whether two e-bill addresses match on Line1, City, and zero-padded zip code. | `SAIF.Domain` — `ProviderMatchBase` |
| GetUniqueLocation | `public static ProviderLocation GetUniqueLocation(IList<ProviderAddress> matchedAddressesListOne, IList<ProviderAddress> matchedAddressesListTwo)` | Intersects two matched-address lists by provider-location id and returns the single common `ProviderLocation`, or `null` when the intersection is not exactly one location ([DOM-BR-025](../../business-rules.md#dom-br-025-payment-resolution)). | `SAIF.Domain` — `ProviderMatchBase` |
| GetMatchingProviderAddresses (single address) | `public static IEnumerable<ProviderAddress> GetMatchingProviderAddresses(EbillAddress ebillAddress, IEnumerable<ProviderAddress> providerAddresses, bool concatenateTwoLineBillAddresses)` | Filters the candidate provider addresses down to those matching the given e-bill address. | `SAIF.Domain` — `ProviderMatchBase` |
| GetMatchingProviderAddresses (address set) | `public static IEnumerable<ProviderAddress> GetMatchingProviderAddresses(IEnumerable<EbillAddress> ebillAddresses, IEnumerable<ProviderAddress> providerAddresses, bool concatenateBillAddresses)` | Filters the candidate provider addresses down to those matching any address in the given e-bill address set. | `SAIF.Domain` — `ProviderMatchBase` |
| RemoveSpecialCharacters | `public static string RemoveSpecialCharacters(string input)` | Strips every character except letters, digits, and spaces from the input, returning `null` for a null input. | `SAIF.Domain` — `ProviderMatchBase` |

## Behavioral notes
- `ProviderIndexerV2` places this rule first (before the facility-name and provider-type filtered variants and before `ThreeAddressNoFacilityMatchesMatchRule`) in the wide rule chain, so it wins ties over the more specific variants ([DOM-BR-028](../../business-rules.md#dom-br-028-v2-indexing))*.
