  1. Design Overview

  2. Generated Packages • fUML.Library.* - generated • fUML.Semantics.* - generated • fUML.Syntax.* - generated • fUML.Test.* - generated • fUML.Utility.* - generated

  3. Custom PackagesTechnologies • Stream Parsing (StAX) • XML Schema • Java Data Binding • XML

  4. Custom Packages • fuml.model.* - runtime metadata • fuml.xmi.* - XMI import processing • fuml.xmi.stream.* - Stream imports • fuml.xmi.bind.* - XML Schema • fuml.xmi.validation .* - XMI Validation • fuml.assembly .* - creates fUML object-graphs • fuml.library .* - loads fUML libraries • fuml.event .* - event support

  5. Custom Packages

  6. org.modeldriven.fuml.model • Runtime available fUML metadata • Loads configurable set of metadata files • Fast Lookups: Package, Classifier, Property, Multiplicity, Defaults etc.. • (XML Schema) Generated Java Model • Performs metadata document merge (initial)

  7. org.modeldriven.fuml.xmi • Visitor pattern based • Encapsulates traversal logic • Abstracts stream/data-binding processing • Abstracts internal/external processing

  8. org.modeldriven.fuml.xmi Class Diagram

  9. org.modeldriven.fuml.xmi.stream • StAX (stream) pull-parser • Flexible – event based and stream based • Efficient – only read events you want • External XMI imports • Internal/External Library imports

  10. org.modeldriven.fuml.xmi.streamClass Diagram

  11. org.modeldriven.fuml.xmi.bind • JAXB Data-Binding based • XML Schema based (problematic for external imports) • Controlled internal metadata imports

  12. org.modeldriven.fuml.xmi.validation • Strict model-driven XMI validation • Visitor pattern based • 2-level Error classification • Detailed error messages • Detachable from execution environment

  13. org.modeldriven.fuml.xmi.validationClass Diagram

  14. org.modeldriven.fuml.assembly • "Direct-to-fUML" approach • Visitor pattern based • 3-stage assembly • primitive features • reference features • hierarchical relationships

  15. org.modeldriven.fuml.assemblyClass Diagram

  16. org.modeldriven.fuml.library • Loads configurable set of XMI files • Performs strict model-driven validation • Assembles fUML object graph(s) • Cross references root elements with URIs

  18. org.modeldriven.fuml.event • Support web applications • Support third-party tools • Discuss!
