* The output stream for writing the attributes of a |
|
38 |
* custom-mapped user-defined type (UDT) back to the database. |

40 |

|
41 |
* <p> |
|
42 |
* When an application calls the |
|
43 |
* method <code>PreparedStatement.setObject</code>, the driver |

44 |
* checks to see whether the value to be written is a UDT with |
|
45 |
* a custom mapping. If it is, there will be an entry in a |
|
46 |
* type map containing the <code>Class</code> object for the |
|
47 |
* class that implements <code>SQLData</code> for this UDT. |
|
48 |
* If the value to be written is an instance of <code>SQLData</code>, |
|
49 |
* the driver will create an instance of <code>SQLOutputImpl</code> |
|
50 |
* and pass it to the method <code>SQLData.writeSQL</code>. |
|
51 |
* The method <code>writeSQL</code> in turn calls the |
|
52 |
* appropriate <code>SQLOutputImpl.writeXXX</code> methods |
|
53 |
* to write data from the <code>SQLData</code> object to |
|
54 |
* the <code>SQLOutputImpl</code> output stream as the |
