You can add an Echo
node to a Flow tab in an orchestration job
to pass inputs that you specify to outputs. This function helps make
jobs more readable.
The Echo node
can also be used to gather output values from around the orchestration
job into a central place. For example, you could have a series of
nodes that output a few values. You can add an echo node to the Flow tab
and map several of those outputs into the Echo node.
The output of the Echo node will contain
the values that you mapped.
Finally, you can use
the Echo node as a placeholder in an orchestration
job. For example, you could have a loop situation with a logical branch.
In this case, you might need both paths from the logical branch to
go back to the looping node. You could establish an Echo node as the
last node in the loop construct instead of having to draw a line from
each of these nodes. Then it would be the only node that loops back
to the beginning.
