APIDocumentation

Created by: Stephan Borg, Last modification: 11 Mar 2006 (11:59 UTC) by Uwe Zimmermann
current APIDocumentation is in pdpDocumentor format, the same as used for Smarty itself - these notes will be brought in line once work is complete !

In an effort to document our code, we've started using code comments and Doxygen (http://www.stack.nl/~dimitri/doxygen/). To browse the API documentation, visit http://your.bitweaver.install/doc/html/.
The Doxygen config file can be found under yourbitweaverinstall/doc/doxygen.cfg.

This page is to help new (and old) bitweaver developers understand how and why we do things the way we do - for API documentation anyway.

Class Doc Comments

Below are some examples of code comments. Please use them as templates - and any improvements should be posted back here.

Class Description


<?php
/**

*
* Currently used to cache user permissions only. Could be used to store blobs to files and other static
* database intensive queries.

class Cachelib
{
...}
?>

So quick explanation. The first two paragraphs are just a description of the class and what it does. Its wise to included where it is used, and if possible point to a code example if its difficult to use.

Doxygen Commands

The next section is a list of fields recognised by Doxygen. For the full listing of Doxygen commands, see http://www.stack.nl/~dimitri/doxygen/commands.html.

@date

http://www.stack.nl/~dimitri/doxygen/commands.html#cmddate
We use date to indicate when the file or library was first created. The date format yyyy/mm/dd is used to standardise with CVS $Date:$ field.

@author

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdauthor
Authors of the file or library are listed here. This command ends with a blank line. Usually CVS name and email address are included.

@version

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdversion
For this we use CVS dynamic fields $Revision: ... $ $Date: ... $ $Author: ... $. This ensure the data is always up to date and maintenance free.
We don't use CVS $Name: xxx $ as they do not work well with CVS merges.

@class

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdclass
This identifies the code as a class to Doxygen which is then used to create graphical inheritence and the like.

Generated Lists

The following are tags that will help our coding efforts.

@todo

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdtodo
This tag is used for something still pending to do. Please don't use FIXME as it does not work with Doxygen. Use @todo to ensure it makes it to the generated list. This command ends with a blank line. The todo command will associate itself to the previous command, so be careful with its placement.

@deprecated

http://www.stack.nl/~dimitri/doxygen/commands.html#cmddeprecated
Deperecate code is to be phased out. Use this to indicate when you plan to phase it out and alternative classed or functions that it has been replaced by.

@bug

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdbug
Indicates where one or more bugs have been reported - is wise to reference a SourceForge bug number.

@test

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdtest
Used to describe a test case - not really sure how we would use this yet.

Variable Description


<?php
    
/**
    * Used to store the directory used to store the cache files.
    */
    
var $_folder;
?>

For variable, just include a line to explain its use.

Function Description


<?php
    
/**
    * Used to retrieve an object if cached.
    * @param key the unique identifier used to retrieve the cached item
    * @return object if cached object exists
    */
    
function getCached($key)
    {...
    }
?>


@param

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdparam
Used in the following way @param parameter_name description, identify each parameter and give a quick description of its use.

@return

http://www.stack.nl/~dimitri/doxygen/commands.html#cmdreturn
Used in the following way @return object_type description, identifies the return object type and give a quick description of what information is returned.

Doxygen Settings

Explain why we use the settings we do...
