| 29 * Test driver for MethodParameters testing. | |
| 30 * <p> | |
| 31 * The intended use of this driver is to run it, giving the name of | |
| 32 * a single class compiled with -parameters as argument. The driver | |
| 33 * will test the specified class, and any nested classes it finds. | |
| 34 * <p> | |
| 35 * Each class is tested in two way. By refelction, and by directly | |
| 36 * checking MethodParameters attributes in the classfile. The checking | |
| 37 * is done using two visitor classes {@link ClassFileVisitor} and | |
| 38 * {@link ReflectionVisitor}. | |
| 39 * <p> | |
| 40 * The {@code ReflectionVisitor} test logically belongs with library tests. | |
| 41 * we wish to reuse the same test-cases, so both test are committed together, | |
| 42 * under langtools. The tests, may be duplicated in the jdk repository. | |
