| CoClasses and Classes | Description |
|---|---|
| FieldMap (esriEditorExt) | The Field map object defines how attributes will get transfered. |
Remarks
A FieldMap contains a number source and target fields for use in attribute transfer.
To create a new FieldMap, instantiate a new FieldMap object then set its source and target feature class via the SourceClass and TargetClass properties. Next set each source and target pair via the SetFieldMap method.
Source/Target field pairs can be can be queried via the FieldMap property, which returns an IEnumFieldMap object containing the field pairs.
A source/target field pair can be removed from a FieldMap by using the DeleteFieldMap method. Only the source field is specified.
