Transition Types

There are different ways to activate a node. It is possible to trigger a node as soon as the first value is available at one of the node’s inputs. It is also possible to delay starting a node until all inputs are available.

There are three different types of transitions:

AND

Transitions of this type require that all transitions of this type leading to the target node provide its input in order to trigger the node.

In the Workflow Creation Tool (WCT), the AND transitions are displayed in black.

OR

These transitions require that at least one transition of this type provides an input in order to trigger the node.

In the WCT, the OR transitions are displayed in green.

RESET

This transition type is used to implement loops. Usually, once the node has all necessary inputs, it becomes active and does not read its inputs again.

Using the reset transition, you can re-initialize the node to the state created, which is especially useful if you want to reuse the node with different data again at a later point. The “RESET” state is propagated by all outgoing transitions (if a node is in the Reset state, all of the following nodes are also in the reset state).

In the WCT, the RESET transitions are displayed using blue color.

Note: Using the Transfer node and the Reset transition types, which enable you to create even complicated logical diagrams, you can further extend the possibilities offered by these three basic types and thus determine exactly the moment and circumstances under which the node should be triggered.

Optional

Transitions of this type do not require any input to trigger the node. It is optional whether the transitions send data to the next node.

In the WCT, the OPTIONAL transitions are displayed in purple/pink.

Time

Time transitions simply trigger the next node without any additional requirements. No input is provided. The transition triggers the next node as soon as the previous node has finished.

In the WCT, the TIME transitions are displayed in green and always have the input and ouput _time.
