|
||
| 69 | Ofrece acceso a todo lo necesario para a?adir un geoproceso
|
||
| 70 | al geoprocessmanager:
|
||
| 71 | a) geoproceso en si
|
||
| 72 | b) panel grafico
|
||
| 73 | c) html descriptivo
|
||
| 74 | d) imagen descriptiva
|
||
| 75 | e) controlador, que lee las entradas de la GUI y se las
|
||
| 76 | pasa al geoproceso
|
||
| 77 | |||
| 78 | ?Como podemos hacer que cuando un desarrollador externo haga una extension
|
||
| 79 | con nuevos geoprocesos, se cosque el GeoprocessManager?
|
||
| 80 | |||
| 81 | 6106 | azabala | El geoprocessmanager tendr? asociada una extension, y en esta
|
| 82 | 6018 | azabala | extension se construye el componente y se a?aden los geoprocesos del core
|
| 83 | (union, diferencia, etc).
|
||
| 84 | Adem?s, construye un punto de extension con el API ExtensionPoints (IverUtiles)
|
||
| 85 | |||
| 86 | En el metodo initialize() de la Extension ANDAMI del GeoprocessManager,
|
||
| 87 | se crear?a el punto de extension "GeoprocessManager".
|
||
| 88 | |||
| 89 | Si desde otro proyecto se quiere crear un geoproceso, y que se muestre en el geoprocess
|
||
| 90 | manager, solo habr?a que construir una extension de andami, y en su metodo initialize
|
||
| 91 | a?adir cada geoproceso nuevo al punto de extension.
|
||
| 92 | |||
| 93 | Luego, desde el GeoprocessManager, en el metodo execute() de la extension
|
||
| 94 | asociada ya se har?a lo siguiente:
|
||
| 95 | ExtensionPoint infoByPoint = (ExtensionPoint)extensionPoints.get("GeoprocessManager");
|
||
| 96 | Iterator infoByPoint =infoByPoint.keySet().iterator();
|
||
| 97 | while( i.hasNext() ) {
|
||
| 98 | String nombre = (String)i.next();
|
||
| 99 | }
|
||
| 100 | Quiz?s sea menos elegante que el mecanismo de los drivers (con su propio
|
||
| 101 | classloader), pero simplifica la gesti?n. No hay que echar ning?n jar
|
||
| 102 | en ning?n directorio. Solo crear las extensiones Andami encargadas de registrar
|
||
| 103 | los nuevos geoprocesos en el punto de extension.
