EditorClass Class

The Object Editor Extension.

Product Availability

Available with ArcGIS Desktop.

Supported Platforms

Windows

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.

Remarks

The Editor object represents the Editor extension to ArcMap - it is the main editing component and the focal point for all other objects in the Editor object model. Although the Editor object is not cocreateable, the Editor object is automatically created whenever a new ArcMap session starts; in fact, all ArcMap extension objects are automatically instantiated when ArcMap is first started.

The Editor object is used to provide a common editing environment for features stored in the ESRI vector geographic datasets: geodatabases, coverages, and shapefiles. Use the Editor object to: create edit operations, create and manage an edit sketch, set the current task, set the target layer, establish a snapping environment, and respond to editor events.

To get a reference to the Editor extension, use IApplication::FindExtensionByCLSID or IApplication::FindExtensionByName.

The Editor manages a collection of related objects including snap agents, edit tasks, and editor extension. References to these objects are provided by the various Editor members. For example, IEditor::Task provides a reference to a specific task given a index.

[C#]

private IEditor m_editor;
private IApplication m_application;

// Would get the app by using hook during implementation of CreateCommand
      ...
      UID editorUid = new UID();
      editorUid.Value = "esriEditor.Editor";
      if (app == null)
        return;

      m_editor = app.FindExtensionByCLSID(editorUid) as IEditor;

//To use the Editor name instead of UID
     ....
       if (app == null)
        return;

m_editor = app.FindExtensionByName("ESRI Object Editor") as IEditor;

[Visual Basic .NET]

In VB.Net you would get the reference to IApplication from hook in the ICommand::OnCreate() hook parameter

Private m_editor As IEditor
Private m_application As IApplication
...
Public Overrides Sub OnCreate(ByVal hook As Object)
    If Not (hook Is Nothing) Then
      If TypeOf (hook) Is IApplication Then
        m_application = CType(hook, IApplication)
      End If
    Else
      Exit Sub
    End If
    Dim editorUid As New UID
    m_application = hook
    editorUid.Value = "esriEditor.Editor"
    m_editor = m_application.FindExtensionByCLSID(editorUid)
  End Sub

'Or it can be found by name. 
...
  ...
  m_editor = m_application.FindExtensionByName("ESRI Object Editor")
End Sub
