The B_Tier table is used to define tiers, which are a collection of subnetworks that share the same level, name restriction, and topology type. Tiers are required for subnetwork management.
| Field | Description |
|---|---|
Target Domain Network | The network domain with which the tier is created in. |
Tier Name | The tier name. |
Rank | The rank of the tier being added. Ranking among tiers controls the order or hierarchy of the subnetworks. Valid inputs for this field are integers 1-n, with one being the highest level in the hierarchy. |
Topology Type | The tier's topology type. The following are valid inputs:
|
Tier Group Name | The existing tier group for which the new tier will be added. |
Subnetwork Field Name | The name of the field that the subnetwork name for this tier is stored in. |
Support Disjoint Subnetwork | Defines if the tier supports disjointed subnetworks. Disjointed subnetwork are subnetworks that belong in the same tier, have the same subnetwork, but are not traversable. If supporting disjointed subnetworks, the field value is set to True. |
Include Barrier Features | Defines whether the traversability barrier features are included in the trace results. Traversability barriers are optional even if they have been preset in the subnetwork definition. If including barriers, set the field value to True. |
Apply Traversability To | The type of traversability to enforce. Traversability scope dictates whether traversability is enforced at junctions, edges, or both.
|
Update Structure Network Containers | Specifies whether the update subnetwork process will update the supported subnetwork name attribute for structure network containers. |
Update Domain Network Containers | Specifies whether the update subnetwork process will update the supported subnetwork name for domain network containers. |
Edit Mode for Default Version | Specifies the edit mode for subnetwork updates on the default version and with file geodatabases. |
Edit Mode for Named Version | Specifies the edit mode for subnetwork updates on a named version. |
Manage IsDirty | Specifies whether the Is dirty attribute in the subnetworks table will be managed by the update subnetwork operation. If no subnetwork controllers are defined for the tier, this parameter uses the default option NOT_MANAGE. |
Include Containers | Specifies whether the container features and objects will be included in the trace results. |
Include Content | Specifies whether the trace will return content of containers in the results. |
Include Structures | Specifies whether structure features and objects will be included in the trace results. |
Validate Locatabitity | Specifies whether an error will be returned during a trace or update subnetwork operation if nonspatial junction or edge objects are encountered without the necessary containment, attachment, or connectivity association in their association hierarchy of the traversed objects. This option ensures that nonspatial objects returned by a trace or update subnetwork operation can be located through an association with features or other locatable objects. |
