* 構(gòu)造函數(shù)
*
* 如果 $source 參數(shù)是一個(gè) TableDataGateway 對(duì)象，則 FLEA_Helper_Pager 會(huì)調(diào)用
* 該 TDG 對(duì)象的 findCount() 和 findAll() 來(lái)確定記錄總數(shù)并返回記錄集。
*
* 如果 $source 參數(shù)是一個(gè)字符串，則假定為 SQL 語(yǔ)句。這時(shí)，F(xiàn)LEA_Helper_Pager
* 不會(huì)自動(dòng)調(diào)用計(jì)算各項(xiàng)分頁(yè)參數(shù)。必須通過(guò) setCount() 方法來(lái)設(shè)置作為分頁(yè)計(jì)算
* 基礎(chǔ)的記錄總數(shù)。
*
* 同時(shí)，如果 $source 參數(shù)為一個(gè)字符串，則不需要 $conditions 和 $sortby 參數(shù)。
* 而且可以通過(guò) setDBO() 方法設(shè)置要使用的數(shù)據(jù)庫(kù)訪問(wèn)對(duì)象。否則 FLEA_Helper_Pager
* 將嘗試獲取一個(gè)默認(rèn)的數(shù)據(jù)庫(kù)訪問(wèn)對(duì)象。
