GeoGirafe is a flexible application to build online geoportals.

/*
 * This class is a used in the state of the application, which will be accessed behind a javascript proxy.
 * This means that each modification made to its properties must come from outside,
 * because they have to be made through the proxy, so that the modification can be listen.
 * Therefore, this class must not contain any method which is updating a value directly
 * For example, any method doing <this.xxx = value> is forbidden here, because the modification be known from the proxy
