| 61 | The <tt class="class">StreamReaderWriter</tt> allows wrapping streams which work in | |
| 62 | both read and write modes. | |
| 63 | ||
| 64 | <P> | |
| 65 | The design is such that one can use the factory functions returned by | |
| 66 | the <tt class="function">lookup()</tt> function to construct the instance. | |

| 85 | all other methods and attribute from the underlying stream. | |
