|

* <P> |
|
| 29 |
* Sirve los datos desde un IBuffer para el driver de escritura. El driver |
|
| 30 |
* de escritura que va a volcar un IBuffer a imagen en disco va solicitando |
|
| 31 |
* los datos por bloques a medida que va salvando los anteriores. Esta clase |
|
| 32 |
* es la encargada de hacer la divisi?n en bloques del buffer a volcar e ir |
|
| 33 |
* sirviendolos a medida que el driver pide m?s datos. |
|
| 34 |
* </P> |
|
| 35 |
* <P> |
|
| 36 |
* Implementa el interfaz IDataWriter que es el que define m?todos necesarios |
|
| 37 |
* para el driver. |
|
| 38 |
* Adem?s es una tarea incrementable por lo que deber? implementar el interfaz |
|
| 39 |
* IIncrementable para poder mostrar el dialogo de incremento de tarea. |
