All subsequent + * calls to this functions return a pointer to the object created + * during the first call. + * + * As the MyMoneyFile object represents the business logic, a storage + * manager must be attached to it. This mechanism allows to use different + * access methods to store the objects. The interface to access such an + * storage manager is defined in the class IMyMoneyStorage. The methods + * attachStorage() and detachStorage() are used to attach/detach a + * storage manager object. The following code can be used to create a + * functional MyMoneyFile instance: + * + * @code + * IMyMoneyStorage *storage = .... + * MyMoneyFile *file = MyMoneyFile::instance(); + * file->attachStorage(storage); + * @endcode + * + * The methods addAccount(), modifyAccount() and removeAccount() implement the + * general account maintenance functions. The method reparentAccount() is + * available to move an account from one superordinate account to another. + * account() and accountList() are used to retrieve a single instance or a + * QValueList of MyMoneyAccount objects. + * + * The methods addInstitution(), modifyInstitution() and removeInstitution() + * implement the general institution maintenance functions. institution() and + * institutionList() are used to retrieve a single instance or a + * QValueList of MyMoneyInstitution objects. + * + * The methods addPayee(), modifyPayee() and removePayee() + * implement the general institution maintenance functions. + * payee() and payeeList() are used to retrieve a single instance or a + * QValueList of MyMoneyPayee objects. + * + * The methods addTransaction(), modifyTransaction() and removeTransaction() + * implement the general transaction maintenance functions. + * transaction() and transactionList() are used to retrieve + * a single instance or a QValueList of MyMoneyTransaction objects. + * + * The methods addSecurity(), modifySecurity() and removeSecurity() + * implement the general access to equities held in the engine. + * + * The methods addCurrency(), modifyCurrency() and removeCurrency() + * implement the general access to multiple currencies held in the engine. + * The methods baseCurrency() and setBaseCurrency() allow to retrieve/set + * the currency selected by the user as base currency. If a currency + * reference is emtpy, it will usually be interpreted as baseCurrency(). + * + * The methods liability(), asset(), expense(), income() and equity() are + * used to retrieve the five standard accounts. isStandardAccount() + * checks if a given accountId references one of the or not. + * setAccountName() is used to specify a name for the standard accounts + * from the GUI. + * + * The MyMoneyFile object emits the dataChanged() signal when data + * has been changed. + * + * For abritrary values that have to be stored with the storage object + * but are of importance to the application only, the object is derived + * for MyMoneyKeyValueContainer which provides a container to store + * these values indexed by an alphanumeric key. + * + * @exception MyMoneyException is thrown whenever an error occurs + * while the engine code is running.
