Edge Source Properties (arcpy)
摘要
提供有关网络数据集中边源的信息。
属性
属性 | 说明 | 数据类型 |
name (只读) |
The name of the feature class associated with this network source. | String |
sourceID (只读) |
The unique identifier of this network source within the network dataset. | Integer |
sourceType (只读) |
The type of network source. This property returns the following keywords:
| String |
elementType (只读) |
Network element type of the network source. This property returns the following keywords:
| String |
fromElevationFieldName (只读) |
The field name in the feature class associated with the given edge feature source that is used as the from elevation field when determining connectivity at coincident end vertices. | String |
toElevationFieldName (只读) |
The field name in the feature class associated with the given edge feature source that is used as the to elevation field when determining connectivity at coincident end vertices. | String |
connectivityPolicies (只读) |
The network dataset edge Connectivity Policies object. This object can be used to determine connectivity information, such as connectivity policies and connectivity groups, used by the edge sources of the network dataset. | Object |
sourceDirections (只读) |
The Network Source Directions object. This object can be used to determine directions properties specific to a particular edge source. The sourceDirections property is available only if the network dataset supports directions which can be determined using the supportsDirections property. | Object |
