| <p> |
| With sign extensions enabled, the marshalled data is interpreted as signed |
| and the data will be appropriately converted into the return type container. |
| With sign extensions disabled, unfilled bits in the container will be set to |
| zero. For example, <code>-1</code> as one signed byte is <code>0xFF</code>. |
| Using <code>readShort</code> with <code>signExtend</code> true, the resultant |
| short will contain <code>0xFFFF</code>, which is <code>-1</code> in Java's |
| signed format. With <code>signExtend</code> false, the resultant short will |
| contain <code>0x00FF</code>, which is <code>255</code>. |
