The Informix® GLS API Programmer's Guide describes the global language support (GLS) application programming interface (API) available in Informix ESQL/C and HCL Informix DataBlade® modules.
applications create instances of public operation classes, which contain pointers to private implementation classes.
The creates C++ objects that encapsulate data retrieved from a database. These value objects are created by the Object Interface for C++ by using an extensible class factory that maps server data types to C++ objects.
When you pass an object to a function by value, the C++ compiler creates a temporary copy of the object to pass to the function. The compiler deletes the object after the function returns. The exact time at which temporary objects are deleted is compiler-dependent. For this reason, your application must not rely on the automatic destruction of temporary objects.
The can be used to create database client applications that run against HCL Informix® databases. However, classes and methods that support version 9,x and 10.x extensibility features are not supported with version 7.x databases.
The provides functionality based on Informix® Global Language Support.
To interact with a database, your C++ client application uses the operation classes of the . These classes have methods for opening database connections, submitting queries, and manipulating database cursors. This section describes how to use these methods.
This section describes the specific value interfaces in detail, and shows how to modify value objects and extract information through the value interfaces into host variables in your application.
When you retrieve values from the HCL Informix® database by using the , the values are returned as value objects. Value objects are created by the Object Interface for C++ by using an extensible class factory that maps Informix data types to C++ objects.
This section is an alphabetized reference that lists and describes the operation classes. Each class has an assignment operator and a copy constructor, which are not listed in the tables of methods.
This section lists and describes the value interfaces. The ITFactoryList and ITPreserveData classes provide support for value interfaces.
