The UltraLite C++ interface provides a set of classes with names that are prefixed by UltraLite_ (for example, UltraLite_Connection and UltraLite_DatabaseManager). Most of the functions for each of these classes implement a function from an underlying interface with the string _iface appended to it. For example, the UltraLite_Connection class implements functions from UltraLite_Connection_iface.
When you explicitly use the UltraLite namespace, you can use a shorter name to refer to each class. Instead of declaring a connection as an UltraLite_Connection object, you can declare it as a Connection object if you are using the UltraLite namespace:
using namespace UltraLite; ULSqlca sqlca; sqlca.Initialize(); DatabaseManager * dbMgr = ULInitDatabaseManager(sqlca); Connection * conn = UL_NULL;
As a result of this architecture, code samples in this chapter use types such as DatabaseManager, Connection, and TableSchema, but links for more information may direct you to UltraLite_DatabaseManager_iface, UltraLite_Connection_iface, and UltraLite_TableSchema_iface, respectively.
