Notes
This method is called to map an input column to a column in the ExternalMetadataColumnCollection of the input. When you are developing a custom data flow component, you override this method to ensure that the input column and the output column match, and to indicate that you want to allow the mapping to occur. For more information about working with external metadata columns, see Implémentation des métadonnées externes.
