updates from a busy week

It's been a busy week and debugging support has seen quite some improvements.

Debugging

  • PathBreakpoint now allows you to select the actor through a dialog rather than having to enter the path manually
  • due to some API changes to input consumers, it is now possible to inspect the current token when stepping through the flow manually, rather than only when reaching a Breakpoint control actor
  • instead of only outputting a textual representation of tokens (inspection panel), a class hierarchy for custom renderers has been implemented plain text (used so far; fallback), images, spreadsheets, reports, Weka Instance(s), timeseries
  • these rendering classes are now also used when previewing items from the internal storage ("storage" tab)
  • started work on adding ability to edit items in internal storage; at this stage primitives and arrays of primitives are supported, as well as objects that can be manipulated through the GenericObjectEditor (more will come)

Here is the summary of the remaining updates:

Fixes

  • The vertical marker paintlet used by the SequencePlotter now uses the actual minimum/maximum of the canvas, not just the one derived from the data

Changes

  • control charts plots can now be initialized with a container from the ControlChart transformer and subsequently display data using the last known limits; furthermore, added support for post-processsing, e.g., limiting the number of data points visible at any given time
  • spreadsheets are now editable in the viewer; the SpreadSheetDisplay sink offers the new "readOnly" option (default = readonly)

Additions

  • OpenFile sink opens the incoming file with the application associated with it as determined by the operating system
  • MissionControl control actor is a minimalistic interface for pausing/resuming/stopping a flow; useful when starting a flow from the commandline using the FlowRunner class instead of from the GUI
  • InputOutputListener control actor allows you to listen in on the tokens go into and coming out from a sub-flow by forwarding them to callable actors for further processing

Thanks for the feedback regarding the debugging functionality and have a good weekend!
