◆ _getCommands()

static ilObjSessionAccess::_getCommands ( )

get commands

this method returns an array of all possible commands/permission combinations

example: $commands = array ( array("permission" => "read", "cmd" => "view", "lang_var" => "show"), array("permission" => "write", "cmd" => "edit", "lang_var" => "edit"), );

Returns: array{permission?:string, cmd?:string, lang_var?:string, default?:bool}[]
