```
public interface ActionInfo
extends Action, ActionListener, Cloneable
```
Esta entidad representa a una accion dentro de gvSIG, que podra ser usada por menus, botones de la toolbar, menus contextuales, o desde cualquier otro elemento de gvSIG que precise invocar a una accion. La accion esta compuesta por una definicion de cual es su etiqueta, su icono, teclas aceleradoras, su tip, o su posicion respecto a otras acciones, junto con una extension (IExtension) que aporta el codigo de la accion. Una accion responde principalmente a cuatro operaciones: - isActive, que nos indica si la accion esta activa, es decir, si debera presentarse al usuario o no. Si una extension no esta activa, los metodos isVisible y isEnabled retornaran siempre false, sin invocar al codigo de la extension asociada a la accion. - isVisible, que nos indica si la accion debera presentarse o no en el interface de usuario. De forma general podemos asumir que cuando se invoque a este metodo se delegara en el metodo isVisible de la extension asociada a la accion. - isEnabled, que nos indica si la accion debera estar habilitada o no en el interface de usuario. De forma general podemos asumir que cuando se invoque a este metodo se delegara en el metodo isEnabled de la extension asociada a la accion. - execute, que provocara que se ejecute el codigo asociado a la accion. De forma general podemos asumir que cuando se invoque a estos metodo se delegara en el metodo execute de la extension asociada a esta accion, pasandole el "command" de la accion como parametro. Ademas de la definicion de la accion, esta tambien puede disponer de una coleccion de acciones hacia las que puede ser redirigida. Esto es, en un momento dado nos puede interesar que cuando sea invocada la accion "A", en lugar de ejecutarse las operaciones de esta, se ejecuten las operaciones de otra accion "B". Esto nos permite atrapar la ejecucion de una accion independientemente de desde donde se este invocando. Cuando una accion tenga asignadas otras acciones a las que redirigir su ejecucion, solo se redigira a una de ellas, la primera en la coleccion de acciones a redirigir que responda "true" a su metodo isEnabled, y en caso de que no responda true ninguna se ejecutara el codigo de la accion original. El orden de la coleccion de acciones a las que redirigir de una accion sera el orden inverso en el que se han ido registrandose las redirecciones. Asi primero se intentara con la ultima redireccion asignada, luego con la anterior, y asi sucesivamente se recorreran todas las redireccion hasta que una responda "true" a su isEnabled, ejecutandose entonces el codigo de esta.
