About

The core of ADAMS is the workflow engine, which follows the philosophy of less is more. Instead of letting the user place operators (or actors in ADAMS terms) on a canvas and then manually connect inputs and outputs, ADAMS uses a tree-like structure. This structure and the control actors define how the data is flowing in the workflow, no explicit connections necessary. The tree-like structure stems from the internal object representation and the nesting of sub-actors within actor-handlers.

Example flow

../../images/flow_snippet.png
  • Horizontal and vertical indicators show how the data flows
  • Each actor has its own icon, since the name can be changed arbitrarily
  • Four types of actors: standalone (red; no input, no output), source (orange; only output), transformer (green; input and output) and sink (greyl; only input)
  • Control actors, i.e., actors that determine the flow of data or flow execution are blue
  • Actors with parameters usually show a so-called quick info on the right-hand side of the name, to give the user an idea how the actor is parametrized without having to open up the dialog with the options.
