Checkstyle Conventions

  • Hidden fields 
    •    public class MyBla {
     private int blubb
     public MyBla(final int blubb) {
     }
     public setBlubb(int blubb) {
        this.blubb = blubb;
     }
   }
      • blubb hides a field Checkstyle warning
      • Final rule enforces that we cannot write blubb = blubb
      • Do we want underscores for member variables? (like in C++)
        • No
      • Is checkstyle able to detect:
        • this.blubb = blubb; OK
        • int blubb; NOTOK
        • (ticket#1443 cds)
  • Property Checkstyle Warning
    • Do not check propery files
    • Do this per project
    • Is this possible to do this globally?
    • (ticket#1444 cds)
    • Decision: We do not adapt the Checkstyle rules

KARMA Demo (ckru, cds)

  • Comments are connected to model elements using a very simple heuristics
  • Heuristics: Spatially closest comments are attached to a model element iff within a given arc radius
  • CI-domain/Router2.kaod seems to be broken
    • Layout problem (GMF editor?)
    • Comments missing (old model?)
    • (ticket#1445 cds)
  • LongRuns? model
    • Interesting comment with line breakes
    • Is correctly attached
    • Comment boxes seem larger than necessary
    • (ticket ckru)

(Comment) Layout Discussion

  • Comments are currently not treated specially (msp)
    • Comments should not be left to the connected nodes but above
    • Use block layout for unconnected elements
      • Priority based, give director highest priority, author-comment the second highest priority
      • New hierarchy level for KGraph? (haf)
      • Same holds for class diagrams (haf)
      • Can the box layouter interpret layout preference annotations (maybe set during the import)? (cds)
        • Special comment types (during import) (rvh)
      • Eclipse View of internally computed layout should be reactivated (haf)
    • 'Rule based layout' (vs. MENGES)
      • Different styles (e.g., depend to the director) (rvh)
  • This should be a special case for 'META LAYOUT' (msp)
    • Generic semantic layout options
    • How can this be connected to KIML and KIVI? (msp, haf)
    • KIML are just special effects for KIVI (haf)
      • Different KIVI combinations that MAY (or may not) configure KIML effects (haf)
      • All layout preferences currently are collected (e.g., from notation model) (msp)
      • Combinations would make persistent changes to the layout preferences (msp)
  • Central Question: What should be persistent and what should not be persistent (rvh)
    • KIML vs KIVI
    • 'KIVI combination scripts' should be persistent (haf)
      • Example: Script an 'alternating layout direction rule' (haf)
      • We do not want to hard code these rules
  • Layout bib vs parametrized layouter (haf, msp)
    • Hierarchy should be invisible to specific layouter (haf)

View Management Demo (haf)

  • Focus on selecion for KSpace editing
  • Hierarchy levels adjustable
  • Focus and context effect
    • List of elements in focus
  • Context should not always be the whole model (rvh)
    • Filter effect, possible? (haf)
    • How many layers do I want to see to the outside
      • Different root element?! (haf)
    • Decision: Two counters needed 
       (FC-Button) Context levels (-)[10](+) Focus level (-)[3](+)
                                All, 1, 2,...          All, 1, 2,...
      • (FC-Button) not pressed per default
      • Focus level select 'all' per default
      • To see whole model: Untoggle (FC-Button) and select 'All' as focus level
    • Different KIVI Eclipse-View better than usage of tool bar?
      • Different parts for different tools (Transformation, Zoom, etc)
      • Support buttons, sliders, links, etc
    • Use customized selection trigger
      • E.g., require additional ALT key to be pressed
      • Use case: Rename a state without changing the context
  • Decouple zooming from selection (ticket#1448 haf)
    • No toggle button but keyboard short cut
    • Decision: (see above)
  • Preference page settings
    • Too far away (ticket#1448 haf)
  • Problem with layer counter
  • Minimial size problem
    • KAOM 'df adapted coding model'
    • Layout of collapsed inner nodes but containing node's size does not change
    • Layout maybe in a wrong model state?
      • Sleeps?! Synchronization problem?
    • Bounding box problem
    • (ticket#1446 msp)
  • No UI code in constructor, otherwise this could end up in a deadlock
  • Turn off validation per default
