Introduction

This page contains some tutorial examples that will help you getting started using StdAir. Most examples show how to construct some simple business objects, i.e., instances of the so-named Business Object Model (BOM).

Preparing the StdAir Project for Development

The source code for these examples can be found in the batches and test/stdair directories. They are compiled along with the rest of the StdAir project. See the User Guide (Users Guide) for more details on how to build the StdAir project.

Build a Predefined BOM Tree

A few steps:

• Instanciate the BOM Root Object
• Instanciate the (Airline) Inventory Object
• Link the Inventory Object with the BOM Root

Instanciate the BOM Root Object

First, a BOM root object (i.e., a root for all the classes in the project) is instantiated by the stdair::STDAIR_ServiceContext context object, when the stdair::STDAIR_Service is itself instantiated. The corresponding StdAir type (class) is stdair::BomRoot.

In the following sample, that object is named ioBomRoot, and is given as input/output parameter of the stdair::CmdBomManager::buildSampleBom() method:

Instanciate the (Airline) Inventory Object

An airline inventory object can then be instantiated. Let us give it the "BA" airline code (corresponding to British Airways) as the object key. That is, an object (let us name it lBAKey) of type (class) stdair::InventoryKey has first to be instantiated.

Thanks to that key, an airline inventory object, i.e. of type (class) stdair::Inventory, can be instantiated. Let us name that airline inventory object lBAInv.

Link the Inventory Object with the BOM Root

Then, both objects have to be linked: the airline inventory object (stdair::Inventory) has to be linked with the root of the BOM tree (stdair::BomRoot). That operation is as simple as using the stdair::FacBomManager::addToListAndMap() method:

Build Another Airline Inventory

Another airline inventory object, corresponding to the Air France (Air France) company, is instantiated the same way:

See the corresponding full program (cmd_bom_manager_cpp) for more details.

Dump The BOM Tree Content

From the BomRoot (of type stdair::BomRoot) object instance, the list of airline inventories (of type stdair::Inventory) can then be retrieved...

... and browsed:

See the corresponding full program (bom_display_cpp) for more details.

Result of the Tutorial Program

When the stdair.cpp program is run (with the -b option), the output should look like:

See the corresponding full program (batch_stdair_cpp) for more details.

Extend the Pre-Defined BOM Tree

Now that we master how to instantiate the pre-defined StdAir classes, let us see how to extend that BOM.

Extend an Airline Inventory Object

For instance, let us assume that some (IT) provider (e.g., you) would like to have a specific implementation of the Inventory object. The corresponding class has just to extend the stdair::Inventory class:

The STL containers have to be defined accordingly too:

See the full class definition (test_archi_inv_hpp) and implementation (test_archi_inv_cpp) for more details.

Build the Specific BOM Objects

The BOM root object (stdair::BomRoot) is instantiated the classical way:

Then, the specific implementation of the airline inventory object (myprovider::Inventory) can be instantiated the same way as a standard Inventory (stdair::Inventory) would be:

Then, the specific implementation of the airline inventory object (myprovider::Inventory) is linked to the root of the BOM tree (stdair::BomRoot) the same way as the standard Inventory (stdair::Inventory) would be:

Another specific airline inventory object is instantiated the same way:

From the BomRoot (of type stdair::BomRoot) object instance, the list of specific airline inventories (of type stdair::Inventory) can then be retrieved...

... and browsed:

Result of the Tutorial Program

When this program is run, the output should look like:

See the corresponding full program (StandardAirlineITTestSuite_cpp) for more details.
