Edge

Edges in workflows

An edge in an UML activity diagram is a connection between any of the nodes in the diagram. The execution result of a node affects how the workflow is continued. Some actions support different continuations which can be selected as actions connected to a following decision node.

Action

The default action is next which commences the workflow to the next step that the edge is incident to. Some of the activity nodes define which other actions may be used and selected in the configuration of the related edge. For example the CSV reader defines the actions next after reading a line and end reached when no more lines are left in the file.
