Directly above in the y-axis objects can be instantiated as an object diagram. Classes can be connected with all sorts of relations (Associations, Compositions, Generalization, etc.), objects...
XJML 1.0 is a platform for Verification and Validation of Java classes
XJML 1.0 actually can reads one Java class and its contract (written in XML) and then executes the next verification techniques:
1. Runtime Assertion Checking (RAC). Using JML4c and JML4rt tools.
2. Extended Static Checking (ESC). Using ESC/Java2.
3. Full Static Program Verification (FSPV). Using the Why platform (tested with Why 2.30 and Why3 0.71)
Objectreferenceanalyser (ORA) helps finding memory leaks, design weaknesses and bugs. The ORA-Framework visualizes objects, their content and relations during runtime of any Java application and is able to persist these findings for subsequent analyze.
