| /** |
| * Tests the methods of {@code ObjectOutputStream.PutField}. 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 ObjectOutputStream.PutField}.</li> |
| * <li>There is no public class that implements |
| * {@code ObjectOutputStream.PutField}. The only way to get an implementation |
| * is by calling {@code ObjectOutputStream.putFields()}.</li> |
| * <li>Invoking the methods of {@code ObjectOutputStream.PutField} only works |
| * from within the private {@code writeObject(ObjectOutputStream)} 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 ObjectOutputStream.PutField}: The serializable helper class |
| * {@code tests.support.Support_GetPutFields} implements |
| * {@code writeObject(ObjectOutputStream)} and uses all {@code putX} methods in |
| * {@code PutField} to write data to the output stream. A second helper class, |
| * {@code tests.support.Support_GetPutFieldsDeprecated}, also uses the |
| * deprecated {@code ObjectOutputStream.PutField.write(ObjectOutput)}. |
| * {@code tests.util.FieldTestFileGenerator} can then be used on a reference |
| * platform to write these two classes to the file {@code testFields.ser} and |
| * {@code testFieldsDeprecated.ser} respectively. |
| * </p> |
| * <p> |
| * The test methods in this class expect to find {@code testFields.ser} and |
| * {@code testFieldsDeprecated.ser} as a resource stored at |
| * {@code tests/api/java/io}. The contents of these files is compared to what |
| * is written when {@code Support_GetPutFields.writeObject(ObjectOutputStream)} |
| * and {@code Support_GetPutFieldsDeprecated.writeObject(ObjectOutputStream)} is |
| * called by the test methods. |
| * </p> |
