# clsSignificantClass

Represents one significant manual class tied to a class-significance control row.

## Purpose

| UpdateUser | `Public Property UpdateUser() As String` | Audit user recorded when the row is updated. |
| ClassSignificance | `Public Property ClassSignificance() As clsClassSignificance` | Related control row that determines whether the manual class is included or excluded. |
| IsClassSignificanceNull | `Public ReadOnly Property IsClassSignificanceNull() As Boolean` | Reports whether the linked class-significance control row is currently unset.* |
| IsExcludedClass | `Public ReadOnly Property IsExcludedClass() As Boolean` | Reports whether the linked class-significance row currently classifies this manual class as excluded ([BR-020](../../../../../business-rules.md#br-020-significant-class-filters-follow-significance)). |
| IsIncludedClass | `Public ReadOnly Property IsIncludedClass() As Boolean` | Reports whether the linked class-significance row currently classifies this manual class as included ([BR-020](../../../../../business-rules.md#br-020-significant-class-filters-follow-significance)). |
| IsValid | `Public Overrides ReadOnly Property IsValid() As Boolean` | Reports whether the significant-class row currently satisfies BOF validation rules.* |

| Equals | `Public Overloads Shared Function Equals(ByVal objA As Object, ByVal objB As Object) As Boolean` | Compares another value with this significant-class row for business-object equality.* |
| Equals | `Public Overloads Overrides Function Equals(ByVal inObject As Object) As Boolean` | Compares another value with this significant-class row for business-object equality.* |
| Equals | `Public Overloads Function Equals(ByVal inObject As clsSignificantClass) As Boolean` | Compares another value with this significant-class row for business-object equality.* |
| GetHashCode | `Public Overrides Function GetHashCode() As Integer` | Returns a hash code aligned with the significant-class row's business identity for collection lookups.* |
| ToString | `Public Overrides Function ToString() As String` | Returns a textual representation of the significant-class row for diagnostics or display.* |
| New | `Public Sub New(ByVal inDataPortalInfo As IDataPortalInfo)` | Creates a new BOF-backed significant-class row instance, optionally seeded with its key values for create or retrieve flows.* |

## Behavioral notes
- This type follows the BOF business-object or collection lifecycle exposed by its public surface.*

## Constraints and usage notes
- Most create, retrieve, and save flows rely on BOF criteria and data-portal behavior inherited from the framework base layer.†
