# clsRateTierFactorCollection
Enumerates risk-type factor 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 factor 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 |
| --- | --- | --- |
| AppliesTo | `Public ReadOnly Property AppliesTo(ByVal inRiskTypeCode As String, ByVal inDate As Date) As clsRateTierFactor` | Returns the factor for the specified risk type that applies on the requested date. |
| CurrentItem | `Public Shadows ReadOnly Property CurrentItem() As clsRateTierFactor` | Exposes the collection's current cursor item as a clsRateTierFactor. |
| Save | `Public Overrides Function Save() As Boolean` | Applies pending edits and persists the collection through the BOF base class. |
| Add | `Public Shadows Function Add(ByVal inRateTierFactor As clsRateTierFactor) As Integer` | Adds a rate tier factor to the managed collection. |
| Contains | `Public Overloads Function Contains(ByVal inRateTierFactor As clsRateTierFactor) As Boolean` | True when an equal rate tier factor is already in the live list. |
| Contains | `Public Overloads Function Contains(ByVal inRiskTypeCode As String, ByVal inEffectiveDate As Date) As Boolean` | True when the live list has a factor with the given risk type and exact effective date. |
| Contains | `Public Overloads Function Contains(ByVal inRiskTypeCode As String) As Boolean` | True when the live list has any factor for the given risk type. |
| Contains | `Public Overloads Function Contains(ByVal inEffectiveDate As Date) As Boolean` | True when the live list has any factor with the given effective date. |
| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inRateTierFactor As clsRateTierFactor) As Boolean` | True when an equal rate tier factor is already staged in the deleted list. |
| ContainsDeleted | `Public Overloads Function ContainsDeleted(ByVal inRiskTypeCode As String, ByVal inEffectiveDate As Date) As Boolean` | True when the deleted list contains a factor with the given risk type and effective date. |
| Remove | `Public Sub Remove(ByVal inRateTierFactor As clsRateTierFactor)` | Removes the supplied factor instance from the live list. |
| Remove | `Public Sub Remove(ByVal inRiskTypeCode As String, ByVal inEffectiveDate As Date)` | Removes the first live factor matching the given risk type and effective date. |
| Where | `Public Function Where(ByVal match As Predicate(Of clsRateTierFactor)) As clsRateTierFactorCollection` | Returns a new collection containing items that satisfy the supplied predicate. |
| GetRateTierFactors | `Public Shared Function GetRateTierFactors(ByVal inDataportal As IDataPortalInfo) As clsRateTierFactorCollection` | Retrieves risk-type factor rows using the key, date, or period criteria supplied by this overload. |
| GetRateTierFactorCollection | `Public Shared Function GetRateTierFactorCollection(ByVal inDataportal As IDataPortalInfo) As clsRateTierFactorCollection` | Retrieves risk-type factor 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.
> **Note:** Statements marked with `†` are derived from dependency library
