clsHazardGroupCollection¶

clsHazardGroupCollection is a read-only business collection (clsBusinessCollection(Of clsHazardGroup)) that retrieves the set of clsHazardGroup records effective as of a given date from the HAZARD_GROUP table, per BR-POL-012. Editing, removal, and general saving are disabled at construction (AllowEdit = False, AllowRemove = False), consistent with hazard-group data being read-only, per BR-POL-011.

Purpose¶

Retrieve all clsHazardGroup records whose effective/expiration date window contains a supplied EffectiveDate, via GetHazardGroups, per BR-POL-012.
Provide indexed (Item) and keyed (ItemByKey) lookup of hazard groups by position or HazardGroupID, consistent with hazard-group identity being the ID alone, per BR-POL-016.
Support membership checks (Contains, ContainsDeleted) and removal (Remove) against the in-memory collection, by object or by HazardGroupID.
Report the collection itself as always valid and never independently savable, reflecting the read-only nature of hazard-group data, per BR-POL-011.

Public members¶

Member	Signature	Purpose
`Item`	`Default Public Overloads ReadOnly Property Item(ByVal Index As Integer) As clsHazardGroup`	The default indexer, returning the `clsHazardGroup` at the specified position.
`ItemByKey`	`Public ReadOnly Property ItemByKey(ByVal inHazardGroupID As String) As clsHazardGroup`	Returns the `clsHazardGroup` matching the specified `HazardGroupID`, or `Nothing` if not found.
`MyCriteria`	`Public ReadOnly Property MyCriteria() As Criteria`	The nested `Criteria` object used to retrieve this collection.
`IsValid`	`Public Overrides ReadOnly Property IsValid() As Boolean`	Always returns `True`; the collection has no independent validation rules.
`IsSavable`	`Public ReadOnly Property IsSavable() As Boolean`	Always returns `False`; the collection cannot be saved, consistent with hazard groups being read-only, per BR-POL-011.
`Contains(inObject)`	`Public Overloads Function Contains(ByVal inObject As clsHazardGroup) As Boolean`	Returns `True` if an equal `clsHazardGroup` exists in the collection.
`Contains(inHazardGroupID)`	`Public Overloads Function Contains(ByVal inHazardGroupID As String) As Boolean`	Returns `True` if a `clsHazardGroup` with the specified ID exists in the collection.
`ContainsDeleted(inObject)`	`Public Overloads Function ContainsDeleted(ByVal inObject As clsHazardGroup) As Boolean`	Returns `True` if an equal `clsHazardGroup` exists in the collection's deleted-items list.
`ContainsDeleted(inHazardGroupID)`	`Public Overloads Function ContainsDeleted(ByVal inHazardGroupID As String) As Boolean`	Returns `True` if a `clsHazardGroup` with the specified ID exists in the collection's deleted-items list.
`Remove(inObject)`	`Public Overloads Sub Remove(ByVal inObject As clsHazardGroup)`	Removes the specified `clsHazardGroup` from the collection.
`Remove(inHazardGroupID)`	`Public Overloads Sub Remove(ByVal inHazardGroupID As String)`	Removes the `clsHazardGroup` matching the specified ID from the collection.
`GetHazardGroupCollection`	`<Obsolete("Use GetHazardGroups instead.")> Public Shared Function GetHazardGroupCollection(ByVal inDataportal As IDataPortalInfo, ByVal inEffectiveDate As Date) As clsHazardGroupCollection`	Retrieves the hazard-group collection effective as of the supplied date. Obsolete — superseded by `GetHazardGroups`.
`GetHazardGroups`	`Public Shared Function GetHazardGroups(ByVal inDataportal As IDataPortalInfo, ByVal inEffectiveDate As Date) As clsHazardGroupCollection`	Retrieves the hazard-group collection effective as of the supplied date, per BR-POL-012. This is the current, non-obsolete entry point.

Inherited public members¶
