|  | <h2>1. Account types<br> | ||
|  | </h2> | ||
|  | LAM currently provides three account types: <span | ||
|  |  style="font-weight: bold;">users, groups, hosts<br> | ||
|  | </span>A module can manage one or more account types.<br> | ||
|  | <br> | ||
|  | The types are specified with <span style="font-weight: bold;">can_manage()</span> | ||
|  | or <span style="font-weight: bold;">meta['account_types']</span>.<br> | ||
|  | <br> | ||
|  | <span style="font-weight: bold; text-decoration: underline;">Example:</span><br | ||
|  |  style="font-weight: bold; text-decoration: underline;"> | ||
|  | <br> | ||
|  | Our <span style="font-style: italic;">ieee802Device</span> | ||
|  | module will be used only for host accounts.<br> | ||

|  | <h2>2. Alias name</h2> | ||
|  | The module name is very limited, therefore every module has an <span | ||
|  |  style="font-style: italic;">alias name</span>. This <span | ||
|  |  style="font-style: italic;">alias name</span> has no limitations and | ||
|  | can be translated. It may contain special characters but make sure that | ||
|  | it does not contain HTML special characters like "<".<br> | ||
|  | The <span style="font-style: italic;">alias name </span>can be the | ||
|  | same for all managed <span style="font-style: italic;">account types</span> | ||
|  | or differ for each type.<br> | ||
|  | <br> | ||
|  | The <span style="font-style: italic;">alias name</span> is specified | ||
|  | with <span style="font-weight: bold;">get_alias()</span> | ||
|  | or <span style="font-weight: bold;">meta['alias']</span>.<br> | ||
|  | <br> | ||
|  | <span style="font-weight: bold; text-decoration: underline;">Example:</span><br | ||
|  |  style="font-weight: bold; text-decoration: underline;"> | ||
|  | <br> | ||
|  | Our <span style="font-style: italic;">ieee802Device</span> | ||
|  | module will get the alias MAC address.<br> | ||

|  | <br> | ||
|  | <h2>3. Dependencies</h2> | ||
|  | Modules can depend on eachother. This is useful if you need to access | ||
|  | attributes from other modules or the managed object classes of your | ||
|  | module are not structural.<br> | ||
|  | <br> | ||
|  | The dependencies are specified with <span style="font-weight: bold;">get_dependencies()</span> | ||
|  | or <span style="font-weight: bold;">meta['dependencies']</span>.<br> | ||
|  | <br> | ||
|  | <span style="font-weight: bold; text-decoration: underline;">Example:</span><br | ||
|  |  style="font-weight: bold; text-decoration: underline;"> | ||
|  | <br> | ||
|  | Our <span style="font-style: italic;">ieee802Device</span> | ||
|  | module depends on the account module (because it is the only structural | ||
|  | module at this time).<br> | ||
|  | <br> | ||
|  | <table style="width: 100%; text-align: left;" class="mod-code" | ||
|  |  border="0" cellpadding="2" cellspacing="2"> | ||

|  | class<br> | ||
|  |     *<br> | ||
|  |     * @return array array with meta data<br> | ||
|  |     */<br> | ||
|  |     <span style="font-weight: bold;">function</span> | ||
|  | get_metaData() {<br> | ||

|  |         // manages host accounts<br> | ||

|  |     </span>$return["account_types"] = array("host");<br | ||
|  |  style="color: rgb(255, 0, 0);"> | ||
|  |         // alias name<br> | ||
|  |         $return["alias"] = _("MAC | ||
|  | address");<br> | ||
|  |         // module dependencies<br> | ||
|  |       <span style="color: rgb(255, 0, 0);">    | ||
|  |     $return['dependencies'] = array('depends' => | ||
|  | array('account'), 'conflicts' => array());</span><br | ||
|  |  style="color: rgb(255, 0, 0);"> | ||
|  |         return $return;<br> | ||
|  |     }<br> | ||

|  | <br> | ||
|  | <h2>4. Messages</h2> | ||
|  | There are many situations where you will display messages to the user. | ||
|  | The modules should define such messages at a common place to make it | ||
|  | easier to modify them without searching the complete file.<br> | ||
|  | The <span style="font-style: italic;">baseModule</span> offers the $<span | ||
|  |  style="font-weight: bold;">messages</span> variable for this. It | ||
|  | should be filled by a function called <span style="font-weight: bold;">load_Messages()</span>.<br> | ||
|  | The <span style="font-style: italic;">baseModule</span> will | ||
|  | automatically check if you have implemented this function and call it | ||
|  | at construction time.<br> | ||
|  | <br> | ||
|  | <span style="font-weight: bold; text-decoration: underline;">Example:</span><br | ||
|  |  style="font-weight: bold; text-decoration: underline;"> | ||
|  | <br> | ||
|  | Now let our <span style="font-style: italic;">ieee802Device</span> | ||
|  | module define a message.<br> | ||
|  | <br> | ||
|  | <table style="width: 100%; text-align: left;" class="mod-code" | ||
|  |  border="0" cellpadding="2" cellspacing="2"> | ||
|  |   <tbody> | ||
|  |     <tr> | ||
|  |       <td style="vertical-align: top;">    /**<br> | ||
|  |     * This function fills the error message array with | ||
|  | messages<br> | ||
|  |     */<br> | ||
|  |     <span style="font-weight: bold;">function</span> <span | ||
|  |  style="color: rgb(255, 0, 0);">load_Messages</span>() {<br> | ||
|  |         $this->messages['mac'][0] = | ||
|  | array('ERROR', 'MAC address is invalid!');  // third array value | ||
|  | is set dynamically<br> | ||
|  |     }<br> | ||
|  |       </td> | ||
