  1. Integration of Java Generics Into The jmle Tool Within The Eclipse IDE Adrian Kostrubiak, 10/7/08

  2. Overview • JML and jmle Review • Article Review • JML: notations and tools supporting detailed design in Java • An overview of JML tools and applications • JACK: A Java Constraint Kit • jmle: A tool for executing JML specifications via constraint programming • Executing JML Specifications of Java Card Applications: A Case Study. • Technology Exposé

  3. JML Review • Exists in annotations before code modules • Behavioral interface specification language • Formally specify module behavior • Java Modeling Language • Design by Contract (DbC) • Java style syntax

  4. JML Example Code /*@ assignable \nothing; ensures \result == j + k; */ int sumOfTwo(int j, int k) { return(j+k); } // can only be called with ints > 0 /*@ assignable myVal; requires j > 0; ensures myVal == \old(myVal) - j; */ void subtract(int j) { myVal = myVal - j; }

  5. jmle Review • jmle • Takes code with JML embedded (comments) • Creates a Java constraint program • Executed with the Java Constraint Kit • jmle in Eclipse • Program itself not run • Runs constraint program • Eases checking and understanding of constraints

  6. Moving Forward With jmle • Currently little generic support in JML and none in jmle • Implementing generics into jmle • Implementing enum types into jmle • Push jmle from mere academic pursuit into actual industry
