Implementation (.c) files
The implementation
(.c) file contains
implementations of operations (methods) whose prototypes are defined
in the specification file.
For example,
when you run the HelloWorld sample,
one of the generated files is Default.c.
Multiline file header
As with specification files, implementation files begin with a multiline header. The
C_CG::File::ImplementationHeader property determines the content of the header. By
default, the value of this property is the same as the SpecificationHeader
property.
Preprocessor directives
The next section of the file lists the specification files of related packages, objects, and
object types. For example, the Default.h file includes the following files:
#include <oxf/RiCTask.h>
#include "Display.h"
To include additional files, use the C_CG::Class::ImpIncludes property.
Serializing global variables for instrumentation
The next section of the implementation file defines global variables and methods for serializing global variables for instrumentation. If the implementation file is for a package, this section also defines methods to initialize the events in the package, and to clean up memory when the package is destroyed.
Method implementations
The next section of the implementation file implements the bodies of both user‑defined (explicit) and automatically generated (implicit) methods.
File footer
As with specification files, the implementation file ends with a multiline footer whose content
is determined by the C_CG::File::ImplementationFooter property. By default, the
value of this property is the same as the SpecificationFooter property.
