Using Comments
Comments are code sections ignored by idlc. In UNOIDL, use C++ style comments. A double slash // marks the rest of the line as comment. Text enclosed between /* and */ is a comment that may span over multiple lines.
service ImageShrink
{
// the following lines define interfaces:
interface org::openoffice::test::XImageShrink; // our home-grown interface
interface com::sun::star::document::XFilter;
/* we could reference other interfaces, services and properties here.
However, the keywords uses and needs are deprecated
*/
};
Based on the above, there are documentation comments that are extracted when idl files are processed with autodoc, the UNOIDL documentation generator. Instead of writing /* or // to mark a plain comment, write /** or /// to create a documentation comment.
/** Don't repeat asterisks within multiple line comments,
* <- as shown here
*/
/// Don't write multiple line documentation comments using triple slashes,
/// since only this last line will make it into the documentation
Our XUnoUrlResolver sample idl file contains plain comments and documentation comments.
/** service <type scope="com::sun::star::bridge">UnoUrlResolver</type>
implements this interface.
*/
interface XUnoUrlResolver: com::sun::star::uno::XInterface
{
// method com::sun::star::bridge::XUnoUrlResolver::resolve
/** resolves an object, on the UNO URL.
*/
...
}
Note the additional <type/> tag in the documentation comment pointing out that the service UnoUrlResolver implements the interface XUnoUrlResolver. This tag becomes a hyperlink in HTML documentation generated from this file. The chapter IDL Documentation Guidelines provides a comprehensive description for UNOIDL documentation comments.
