Engine中提供IDatasetEdit来判断数据是否处于编辑状态,我们知道,在ArcMap中,进行编辑的不一定都是要素类,也可以是表,网络几何等.以下能在ArcMap中进行编辑的数据都实现了 IDatasetEdit接口:
Classes that implement IDatasetEdit
| Classes | Description |
|---|---|
| AttributedRelationshipClass | Esri Attributed Relationship Class object. |
| CadastralFabric (esriGeoDatabaseExtensions) | A container for querying information about a cadastral fabric. |
| CadastralFabricFDExtension (esriGeoDatabaseExtensions) | A container for describing this cadastral fabric's feature dataset extension properties. |
| FeatureClass | Esri Feature Class object. |
| FeatureDataset | Esri Feature Dataset object. |
| GeometricNetwork | Esri Geometric Network object. |
| NetworkDataset | A container for querying information about a network dataset. |
| NetworkDatasetFDExtension | A container for describing this network dataset's feature dataset extension properties. |
| NetworkDatasetWorkspaceExtension | A container for describing this network dataset's workspace extension properties. |
| ObjectClass | Esri Object Class object. |
| RasterCatalog | A collection of raster datasets in a Geodatabase table. |
| RouteEventSource (esriLocation) | Route event source object. |
| SchematicDiagramClass (esriSchematic) | Schematic diagram class object. |
| SchematicElementClass (esriSchematic) | Schematic element class object. |
| SchematicInMemoryFeatureClass (esriSchematic) | Schematic in memory feature class object. |
| StreetNetwork | A container for describing a street network. |
| Table | Esri Table object. |
| TemporalFeatureClass (esriTrackingAnalyst) | Controls settings for the temporal feature class. |
| TemporalRecordSet (esriTrackingAnalyst) | Defines the COM coclass for the TemporalRecordSet COM object. |
| Topology | Esri Topology object. |
| UtilityNetwork | A container for describing a utility network. |
| XYEventSource | XY event source object. |
如下代码演示了判断要素类是否处于编辑状态:
private void IsEditing() {
ESRI.ArcGIS.Carto.ILayer lyr = mapCtrl_main.get_Layer();
ESRI.ArcGIS.Carto.IFeatureLayer flyr = (ESRI.ArcGIS.Carto.IFeatureLayer)lyr;
ESRI.ArcGIS.Geodatabase.IFeatureClass fclass = flyr.FeatureClass;
ESRI.ArcGIS.Geodatabase.IDatasetEdit dsEdit = (ESRI.ArcGIS.Geodatabase.IDatasetEdit)fclass;
bool isEditing = dsEdit.IsBeingEdited();
}
