- 7. ● List ○ node mappings to define list elements ● Free form Viewpoint specification model Several kind of containers ● Compartments ○ container mappings to define compartments ○ fixed or dynamic ○ vertical / horizontal stacks Supported children presentations:
- 8. Viewpoint specification model ● Domain Class Naive approach ● No Semantic Candidates Expression ● Precondition expression to filter elements Note: ● Green: EClass qualified name ● Yellow: interpreted expression

- 11. Mapping Evaluation ● Empty semantic candidates expression -> Sirius looks for candidates into all loaded semantic/domain model ● eAllContents() on each domain resource content ● Not efficient ● No control on the displayed elements Naive approach
- 13. Diagram elements computation From the element to refresh (and its description/mapping): ● Get available mappings to refresh ○ activated Viewpoints, activated Layers ○ children mappings + reused mappings
- 14. Diagram elements computation ● For each mapping found ○ Evaluation of the semantic candidates expression from the current domain element (or eAllContents() on each domain resource if empty) ○ Filter with the specified domain class ○ On each candidate, evaluate the precondition ○ Create the diagram element, assign a style From the element to refresh (and its description/mapping):
- 15. Diagram elements computation empty semantic candidates + big models + many (sub) mappings + many complex precondition expressions ⇒ Poor performances Worst conditions
- 16. Diagram elements computation Try as much as possible to write efficient semantic candidates expression: ● Avoid empty semantic candidates expression and eAllContents when possible ● Follow the structural features defined in the meta model ● Use the inverse cross references to look for elements with a reference to another element. ○ eInverse(Type) in AQL and Acceleo3 ○ access to the ECrossReferenceAdapter from a Java service ● Use the specialized interpreters when possible (var: / service: / feature:) ● Try to integrate your precondition in your semantic candidate expression aql: mainExpression -> select( e | e.precondition) Your role

- 21. Mapping synchronization ● Synchronized mapping: Sirius looks for mapping candidates ● Unsynchronized mapping: Sirius refreshes styles and sub elements. ● Allows to create contextual diagrams: ○ User controls the elements he wants to see on his diagram ○ Sirius does not create elements for non-synchronized mappings ○ Delete from diagram is enabled
- 22. Mapping synchronization ● Specifier must create some ‘insertion’ tools ○ Selection Wizards ○ Drop tools (from Model Explorer) ○ Double clics ○ Menus ● Mappings of edge, border nodes, list elements often put as synchronized
- 23. Advanced tools: Direct edit (F2) Easy edit mask creation ● {0} : {1} ● split user text into String variables
- 24. Advanced tools: Java service Java services can be used to do more. Ecore Tools: direct edit of EStructuralFeatures (nodes/edges) ● « Something » => change name of feature ● «:SomeType » => only change the eType ● «1» => only set cardinality to 1..x ● « * » => only set cardinality to x..* ● « /Something » => make the feature derived ● « = something » => set the default value literal ● [...]

- 39. User Color Palette ● User fixed color: RGB, System color chooser ● Computed Color: interpreted expression to compute R, G, B ● Interpolated Color ○ Define several color steps (value/color) ○ Expression to compute a value from the element to decorate
- 40. Conditional Styles ● Available for every kind of mapping ● 0..* conditional style ● Each conditional style contains a different style
- 43. Conditional Styles Edge styles ● Routing style (oblique, manhattan, tree) ● Line style ● Source / Target arrows ● Begin / Center / End labels
- 44. Conditional Styles ● Precondition must be exclusive ● Sirius takes the first whose precondition evaluation returns true. ● The ‘default’ style is taken if no conditional style can be applied
- 45. Style Customizations ● Defined in a Layer ● Style Customization has a precondition ● More fine grained customization (than the Conditional Styles) ● Property Customization ○ target one EStructuralFeature of the Sirius style descriptions ○ applied on all styles or selected ones

- 50. Provided interpreters AQL ● stronger type information than Acceleo3 - allows stronger type analysis ● implementation specifically tailored for the Sirius use case ● complex or custom logic: Java Services ● predicatable ordering and performance overhad ● simple for querying EMF models ● evaluation: fast and collect errors ● validation: strong and precise Recommended query language for Sirius 3.1.0
- 51. Takeaways Help Sirius find the elements to display Use AQL and the specific interpreters Think about your models topology Use inverse cross references Big models? Remember the contextual diagrams Help the user with advanced tools Conditional styles completely change the appearance of an element Style customizations allow a more fine grained customization Use Viewpoint, Diagram Extensions, Layers to deal with different aspects in your modelers Sys2Soft Performances depends on your .odesign specification Measure, Improve, Repeat
