Examples with ClassInfo org.osjava.jardiff.ClassInfo used on opensource projects

Example 1 with ClassInfo

use of org.osjava.jardiff.ClassInfo in project semantic-versioning by jeluard.

the class ClassInheritanceTest method addClassInfo.

private void addClassInfo(Map<String, ClassInfo> classMap, Class klass, JarDiff jd) throws Exception {
    ClassInfo classInfo = jd.loadClassInfo(new ClassReader(klass.getName()));
    classMap.put(classInfo.getName(), classInfo);
}

Example 2 with ClassInfo

use of org.osjava.jardiff.ClassInfo in project semantic-versioning by jeluard.

the class ClassInheritanceTest method shouldInheritedMethodMatchImplementedMethod.

@Test

     * The situation we are testing is as follows:
     * Abstract class InheritanceRoot is initially implemented directly by ClassA.
     * ClassA is later modified to extend another implementation of InheritanceRoot
     * and the methods required by InheritanceRoot are now removed from ClassA directly,
     * and instead inherited from the new parent, DirectDescendant. For the purposes of
     * this test, this new ClassA is represented by ClassB (as we can't have the same
     * class declared twice in a test -- in real life, this would both be ClassA's,
     * in different jars).
