Using the transformer Drag-and-Insert function is the easiest way to insert and connect transformers into an existing workspace. It virtually eliminates the need to manually re-establish connections.
You can "drag and insert" a transformer into an existing connection (or "pipeline"). When you release the transformer, it is set in place. A wizard sets destination node and output port (if there�s more than one). FME then makes feature and attribute connections automatically. If either object has multiple input or output ports, you�ll also be prompted to choose which specific port(s) to connect.
Tip: You can change the default port for the automatic input and output connections. See FME Transformers Options. |
You can also insert into multiple pipelines at once by highlighting a transformer input/output port.
This transformer is dragged to the proper input port (highlighted in pink):
When it is released, the transformer is now in position.
Tip – Reversing the Insertion Point:
|
You can connect a single transformer into multiple input ports that require separate connections.
This example shows how to insert a Clipper transformer. In this case, there are multiple input ports requiring separate connections.
The first connection is easy to make with the drag-and-insert function�
Dragging a transformer that is already inserted still causes a highlight point to appear, and connections to be highlighted. You can make a second insertion with the same transformer, but onto the other link�
The Clipper is now correctly inserted.
Note: You cannot insert a transformer in a position that would cause a loop in the workflow � such invalid connections will not even be highlighted.
This feature is enabled in Workbench by default. To disable it and use
manual connections only, click the drag-and-insert tool .
