# clsRateTierCollection
Enumerates risk-type code rows. Its factory methods retrieve these rows through BOF criteria objects, and its helpers expose the keyed or effective-dated filters callers use after load.
## Purpose
- Enumerates risk-type code rows.
- Its factory methods retrieve these rows through BOF criteria objects, and its helpers expose the keyed or effective-dated filters callers use after load.
## Context
- Namespace: `SAIF.Business.Policy.Rating`
- Assembly/package: `SAIF.Business.Policy.Rating`
## Public members
| Member | Signature | Purpose |
| --- | --- | --- |
| CurrentItem | `Public Shadows ReadOnly Property CurrentItem() As clsRateTier` | The collection item at the current BOF cursor position, cast to `clsRateTier`. |
| Defaults | `Public ReadOnly Property Defaults() As clsRateTierCollection` | Subset containing only rate tiers flagged as default tiers. |
| MarketType | `Public ReadOnly Property MarketType(ByVal inMarketType As Policy.Enums.MarketTypes) As clsRateTierCollection` | Subset containing only rate tiers whose `MarketType` matches the requested policy market. |
| Active | `Public ReadOnly Property Active(ByVal inDate As Date) As clsRateTierCollection` | Subset containing only rate tiers whose effective span includes the requested date. |
| ManagedCareOrganization | `Public ReadOnly Property ManagedCareOrganization(Optional ByVal inIsManagedCareOrganization As Boolean = True) As clsRateTierCollection` | Subset containing only rate tiers whose managed-care-organization flag matches the requested value. |
| IntegratedHealthCare | `Public ReadOnly Property IntegratedHealthCare(Optional ByVal inIsIntegratedHealthCare As Boolean = True) As clsRateTierCollection` | Subset containing only rate tiers whose integrated-health-care flag matches the requested value. |
| Subset | `Public ReadOnly Property Subset(ByVal inMarketType As Policy.Enums.MarketTypes, ByVal inDate As Date, ByVal inIsManagedCareOrganization As Boolean, ByVal inIsIntegratedHealthCare As Boolean) As clsRateTierCollection` | Combined filter that narrows the collection by market type, active date, managed-care status, and integrated-health-care status. |
| Add | `Public Shadows Function Add(ByVal inRateTier As clsRateTier) As Integer` | Adds the supplied rate-tier object to the collection active list through the BOF base class. |
| Contains | `Public Overloads Function Contains(ByVal inRateTier As clsRateTier) As Boolean` | Reports whether the active collection contains a rate tier equal to the supplied object. |
| Contains | `Public Overloads Function Contains(ByVal inCode As String) As Boolean` | Reports whether the active collection contains a rate tier whose `Code` matches the supplied value. |
| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inRateTier As clsRateTier) As Boolean` | Reports whether the deleted-items list contains a rate tier equal to the supplied object. |
| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inCode As String) As Boolean` | Reports whether the deleted-items list contains a rate tier matching the supplied code. |
| Remove | `Public Sub Remove(ByVal inRateTier As clsRateTier)` | Removes the supplied rate-tier object from the active collection list. |
| Remove | `Public Sub Remove(ByVal inCode As String)` | Removes the first active rate tier whose `Code` matches the supplied value. |
| GetRateTiers | `Public Shared Function GetRateTiers(ByVal inDataportal As IDataPortalInfo) As clsRateTierCollection` | Retrieves risk-type code rows using the key, date, or period criteria supplied by this overload. |
| GetRateTiers | `Public Shared Function GetRateTiers(ByVal inDataportal As IDataPortalInfo, ByVal inMarketType As Policy.Enums.MarketTypes, ByVal inEffectiveDate As Date, Optional ByVal inIsManagedCareOrganization As Boolean = False, Optional ByVal inIsIntegratedHealthCare As Boolean = False) As clsRateTierCollection` | Retrieves risk-type code rows using the key, date, or period criteria supplied by this overload. |
## Inherited public members
| Member | Signature | Purpose | Origin |
| --- | --- | --- | --- |
| First | `Sub First()` | Moves collection traversal to the first item.† | `SAIF.Framework.Core` — `clsBusinessCollectionBase` |
| Last | `Sub Last()` | Moves collection traversal to the last item.† | `SAIF.Framework.Core` — `clsBusinessCollectionBase` |
| Next | `Sub Next()` | Advances collection traversal to the next item.† | `SAIF.Framework.Core` — `clsBusinessCollectionBase` |
| Previous | `Sub Previous()` | Moves collection traversal to the previous item.† | `SAIF.Framework.Core` — `clsBusinessCollectionBase` |
| Error | `ReadOnly Property Error As String` | Surfaces collection-level broken-rule text through `IDataErrorInfo`.† | `SAIF.Framework.Core` — `clsBusinessCollectionBase` |
## Behavioral notes
- Rows are loaded through the BOF data portal first; the collection then applies any additional in-memory filtering or keyed selection.
## Constraints and usage notes
- Lookups that do not find a matching row return `Nothing` or an empty filtered collection, so callers should handle missing results explicitly.
