  1. Extension Package: Behaviour Types Thomas Deiß Nokia Siemens Networks MTS#48

  2. Summary • CRs resolved • CR412: Function Reference • CR2012: runs on self • Status • Technical issues resolved, package written • Missing • C++ and XML language mapping for TCI • Proposal for operational semantics of one operation exists • Needs to be checked and applied to 3 other operations similarly • Open Issue: • package is written as change to main parts of the TTCN-3 standard • Is this readable enough? Thomas Deiß / Advanced Typing / March 2009

  3. Behaviour types • type function MyFunc3 ( in integer p1 ) return charstring; • function blanks (in integer p1) return charstring { // return a charstring of p1 blank chars} • //function referencevar MyFunc3 myVar1 := blanks; • var MyFunc3 myVar2 := int2char; • var MyFunc3 myVar3 := null; Thomas Deiß / Advanced Typing / March 2009

  4. Behaviour Types Usage • Test configurations • State machine implementation • Flexible default handling • Load and robustness tests • Behaviour types for • Functions • Altsteps • Testcases Thomas Deiß / Advanced Typing / March 2009

  5. Usage of behaviours • Pass as actual parameters • Compare • Send to other components • log • Apply to arguments • Also activate, start, execute Thomas Deiß / Advanced Typing / March 2009

  6. Semantics • Instead of considering function, altstep, test case names as literals, evaluate an expression that results in a behaviour Thomas Deiß / Advanced Typing / March 2009

  7. TRI / TCI • TRI: no effect • TCI • New abstract types for function, altstep, testcase Thomas Deiß / Advanced Typing / March 2009

  8. Next steps • Proposal: • Add C++ and XML language mappings • Finalize operational semantics • Then proceed to approval Thomas Deiß / Advanced Typing / March 2009
