Rules for link validation

There are certain rules according to which a link can exist or not. These rules are:

• There can be only one link between two nodes in a workflow. If there is a need to map outputs of one node to specific inputs of the other node this is done through Data mapping and not by adding multiple links between the two nodes.

• Each graphInput and graphOutput node can be connected to only one node when creating a workflow that can be used as a subworkflow.

• A subgraph can be connected to different nodes as long as it has multiple inputs and/or outputs since each input/output can be connected to one node.
