| /** |
| * Tests the methods of {@code ObjectInputStream.GetField}. Three things make |
| * this class somewhat difficult to test: |
| * <ol> |
| * <li>It is a completely abstract class; none of the methods is implemented in |
| * {@code ObjectInputStream.GetField}.</li> |
| * <li>There is no public class that implements |
| * {@code ObjectInputStream.GetField}. The only way to get an implementation is |
| * by calling {@code ObjectInputStream.getFields()}.</li> |
| * <li>Invoking {@code ObjectOutputStream.getFields()} only works from within |
| * the private {@code readObject(ObjectInputStream)} method of a class that |
| * implements {@code Serializable}; an exception is thrown otherwise.</li> |
| * </ol> |
| * <p> |
| * Given these restrictions, an indirect approach is used to test |
| * {@code ObjectInputStream.GetField}: Three serializable helper classes in |
| * package {@code tests.support} ({@code Support_GetPutFields}, |
| * {@code Support_GetPutFieldsDeprecated} and |
| * {@code Support_GetPutFieldsDefaulted}) implement |
| * {@code readObject(ObjectInputStream)} to read data from an input stream. |
| * This input stream in turn reads from one of the corresponding files |
| * ({@code testFields.ser}, {@code testFieldsDeprecated.ser} and |
| * {@code testFieldsDefaulted.ser}) that have been created with |
| * {@code tests.util.FieldTestFileGenerator} on a reference platform. |
| * </p> |
| * <p> |
| * The test method in this class expects to find the reference files as a |
| * resource stored at {@code tests/api/java/io}. |
| * </p> |
