php – CodeIgniter第三方类不加载

我已经尝试将这个类添加到自动加载中,以及在我的控制器$this-> load-> library(‘dash’)中,但是这也给出了相同的错误.

我已经检查了dash.php,并发现下面的方法私有函数__example __(),但不能理解开发人员在评论中说什么.

class Dash
{
    private function __example__()
    {
        /*
         * This function is purely to show an example of a dashboard method to place
         * within your own controller.
         */

        // load third_party hArpanet dashboard library
        $this->load->add_package_path(APPPATH.'third_party/hArpanet/hDash/');
        $dash =& $this->load->library('dash');
        $this->load->remove_package_path(APPPATH.'third_party/hArpanet/hDash/');

        // configure dashboard widgets - format: type,src,title,cols,alt (for images)
        $dash->widgets = array(

                    array('type'=>'oop','src'=>'test_dash','title'=>'Test OOP Widget','cols'=>3),// if 'title' is set to FALSE,the title block is omitted entirely
                    // note: this is an 'html' widget but is being fed content from a local method
                    array('type'=>'html','src'=>self::test_method(),'title'=>false,array('type'=>'file','src'=>'saf_inv.htm','title'=>'Safety Investigation'),// multi-content widget - set widget title in outer array (also note use of CI anchor to create a link)
                    array('title'=>anchor('tz','TARGET ZERO'),// sub-content follows same array format as single content widget
                            // 'img' content can also have an 'alt' text
                            array('type'=>'img','src'=>'saf_tzout.gif','alt'=>'Action Completed'),'src'=>'saf_tz.htm'),'src'=>'ave_close.htm','title'=>'Average Time to Close')
                            ),'src'=>'saf_meet.htm','title'=>'Safety Meeting'),'src'=>'saf_acc.htm','title'=>'Accident Investigation'),'src'=>'saf_hazmat.htm','title'=>anchor('hazmat','HAZMAT')),'src'=>'saf_cont.htm','title'=>'Loss of Containment'),'src'=>'saf_worksinfo.htm','title'=>'Works Information'),// an action widget - 'clear' will generate a blank widget with a style of clear:both
                    array('type'=>'clear'),// multi-content widget - width can be set using the 'cols' param in outer array
                    array('title'=>'RAG Report','cols' => 2,'src'=>'saf_rag.htm'),array('type'=>'img','src'=>'ProcSaf.gif')),'src'=>'saf_chrom.htm','title'=>'Chrome checks'),);

        // populate the view variable
        $widgets = $dash->build('safety');

        // render the dashboard
        $this->load->view('layout_default',$widgets);

    }
...................

} // end of Dash class

安装路径是root / application / third_party / hArpanet / hDash / libraries / dash.php

如何将此类加载到我的系统并使用小部件？
