/**
 * Meme chose que la classe org.apache.ojb.broker.accesslayer.StatementManager. 
 * Permet de gerer les structures Oracle en passant un parametre de connection a un endroit.
 * Par rapport a la version originale de StatementManager :
 *  les imports ont ete reorganises,
 *  le constructeur renomme, 
 *  changement de la nature de l'attribut m_broker en GeOxygenePersistenceBrokerImpl,
 *  changement d'une affectation de cet attribut dans le constructeur,
 *  un ajout dans la methode bindStatementValue(),
 *  changement dans getAllValues,
 *  changement dans getKeyValues (2 methodes),
 *  changement dans getNonKeyValues
 *  modification des " setNull " (plusieurs) pour gerer le cas de l'ecriture de geometries nulles.
 * 
 * AB 11 juillet 2005 : 
 * <br> Utilisation des noms de classes et de la r閒lection pour permettre la compilation s閜閞閑 pour Oracle.
 * <br> Patch pour permettre l'utilisation de la meme classe de "FieldConversion" pour Oracle et Postgis. 
 * 
 * @author Thierry Badard & Arnaud Braun
