EGL open source strategy (featuring demos of vendor developed tools and Android application generator). See www.eglcon.org for more information.

1. EGL Open: Extensible Model Compilers Tim W Wilson – EGL Chief Architect

2. Evolution of Language Abstraction Hardware OS Runtime Platform Assembler C, COBOL Java EGL One One One One One One One Many Many Many One Single Machine Multiple Machine Future One Many Evolution of Execution Environment Evolution of Programming Languages Range of Deployment Options

9. EDT – Code generation process Java EGL Source Code EGL Compiler Model Extensible Code Generation Framework Java JavaScript C/C++ .Net … Pluggable Generators Eclipse JEE Dojo Pluggable Extension Examples Possible Android COBOL CICS/IMS

10. Module Structure of EDT: org.eclipse.edt org.eclipse.edt.ide org.eclipse.edt.core org.eclipse.edt.gen

12. The MOF (Meta Object Framework) Model

14. EGL Meta Model

16. XML Serialization of EClass - StructPart This object is an instance of EClass Instances of org.eclipse.edt.mof.egl.Field

17. XML Serialization of ExternalType - Customer This object is an instance of org.eclipse.edt.mof.egl.ExternalType Instances of org.eclipse.edt.mof.egl.Field

23. Android Generator: an example

25. UI Programming Model Example: Define Concepts in EGL Abstract concepts defined using Externaltype with AbstractType stereotype Event handlers modeled as Delegates Inheritance modeled directly Externaltype declarations allow for full Class modeling

26. UI Programming Model Example: Define Concepts in EGL Core UI Concepts Stereotypes for implementation Concrete Widgets

27. Example Usage: Mortgage Calculator Event handler declaration Stereotype used to implement a Window Similar conceptually to RUIHandler Invocation of the Amortize Service Declaration of Widgets and properties

29. Create the AndroidGenerator class Android generator extends core Java generator Adds command line parameters as necessary Define where the configuration is for adding and overriding code generation templates Define where the configuration is for mapping abstract types to concrete classes in the runtime

30. Create Necessary Templates Override existing method from Template from Core Template method invocation

31. Map Model to Android Templates Mapping of model classes to their templates

32. Running Mortgage Calculator on Android Emulator

33. Demo

34. EGL open Tools – Xtool and Xref Lars Kaare Andersen Xact Consulting A/S CTO and Partner

38. EGL code relations – direct and indirect use of parts Program2 Program1 Record2 Program3 Program4 Function1 Function2 Function3 Function4 Record4 Record3 Record1

39. EGL program relations and usages Test case 1 Test case 2 Test case 3 Sub System xx Program1 Program4 Program2 Program3 Program5 Program6 Program7 Program10 Program8 Program9 Program11 Program12 Program13 Program16 Program14 Program15 Program17 Program18

41. Version Control related to States (Test, Systemtest, Production) Limited to: Latest or State Version in State

43. Xref – Search for parts

44. Xref Information - Call Stack

45. Xref – Search for References

46. Xtool - Synchronize

47. Xtool – Main package View
