Informix® Object Interface for C++
Guide
The
Informix® Object Interface for C++ Programmer's Guide
describes how to develop
HCL Informix®
client applications by using the object-oriented C++ programming language.
Architecture of the object interface for C++
The encapsulates
HCL Informix®
database server features into a class hierarchy.
Operation classes
applications create instances of public operation classes, which contain pointers to private implementation classes.
Value interfaces and value objects
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.
Class hierarchy
Implementation notes
This section describes the programming restrictions and practices.
Restrictions
Passing objects—compiler dependency
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.
Informix®
database server compatibility
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.
Globalization
The provides functionality based on
Informix®
Global Language Support.
Issue database queries and retrieve results
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.
Access data values
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.
Create and extend value objects
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.
Operation class reference
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.
Value interface reference
This section lists and describes the value interfaces. The ITFactoryList and ITPreserveData classes provide support for value interfaces.
Appendixes
This section contains additional reference information.
