class IMyMoneyStorage;
class MyMoneyTransactionFilter;
/**
* This class represents the interface to the MyMoney engine.
* For historical reasons it is still called MyMoneyFile.
* It is implemented using the singleton pattern and thus only
* exists once for each running instance of an application.
*
* The instance of the MyMoneyFile object is accessed as follows:
*
* @code
* MyMoneyFile *file = MyMoneyFile::instance();
* file->anyMemberFunction();
* @endcode
*
* The first line of the above code creates a unique MyMoneyFile
* object if it is called for the first time ever. 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
* TQValueList 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
* TQValueList 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
* TQValueList 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 TQValueList 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. The MyMoneyException:: object
* describes the problem.
