VxWorks 5.5 BSP Developer’s Guide In Tornado 2.x, a code generator outputs the system configuration files, basing them only on those components selected for configuration by the user. The overall configuration of a project is the list of included components and their properties. Details of how the project facility and code generator work can be found in the Tornado User’s Guide: Projects. In the past, you thought of components as the code and parameters included in the system by making modifications to the configuration files (config.h or configAll.h), as follows: #define INCLUDE_FOO For Tornado 2.x, you describe a component by defining its properties in a CDF, as follows: Component INCLUDE_FOO { // Define a component called INCLUDE_FOO. NAME Foo example component SYNOPSIS This is just an example component ... // other properties } Component properties fall into one of the following four categories: ■ ■ ■ Code. This can be a combination or subset of object code (modules) and source code (configlettes and stubs) used in the build of a project. Configuration Information. CDL provides a rich set of properties to be used to describe a component. These can be specified, altered, added, or eliminated. Parameters are configurable properties expressed as data types. These are typically preprocessor macros used within a component’s configuration code. There is a separate CDL object used to define parameters. Integration Information. These properties control how a component is integrated into an executable “system image,” for example, an initialization routine and a description of when in the initialization sequence that routine should be called. Integration properties also define dependencies among components, replacing the #ifdef/#endif statements that proliferated in previous versions of Tornado. 114
6 Components ■ User Presentation. A number of properties control how a component is presented to the user, that is, how a component appears in the Tornado GUI. For example, presentation properties define characteristics as basic as a component’s name and a brief synopsis of the component’s functionality. They also affect where in the project facility component hierarchy a component, folder, or selection is displayed. You can also specify HTML reference pages as support material for a particular component. 6.2.2 CDL Object Types, p.115 goes into greater detail about the various properties and their uses. For more information about working with component description files, see 6.3 Creating Components, p.125 and 6.4 Releasing Components, p.135. 6 6.2.2 CDL Object Types The Component Description Language supports a number of object classes. With the proliferation of components, a means of grouping them into related subsystems has been developed—called folders and selections, each of which is described by a CDL object. A means of specifying a component’s initialization order is provided by initialization groups, another object type. Of course, CDL provides an object to define a component and its properties. And there is an additional object type for defining parameters, which are component properties expressed as data types. Figure 6-1 shows the project facility component hierarchy. Entries (components, selections, and folders) appear in boldface in the project facility component hierarchy when they are included in the configuration, in “plainface” when they are not included, and in italics when they are not installed (that is, when a CDF already describes a component, but the component’s modules have not been installed.) For the complete syntax of each CDL object type, see E.1 Component Description Language (CDL), p.231. 115
