error handler

基本解釋

Note that if no error handler is attached, the default implementation throws a SAXParseException on any validation error.
注意，如果沒有指定錯誤處理程序，則默認的實現(xiàn)對任何驗證錯誤都拋出 SAXParseException 異常。
You can then work with the XMLReader instance as you would with a straight SAX application which of course includes setting an error handler.
接下來可以像處理一個簡單 SAX 應用程序一樣處理 XMLReader 實例，并設置一個錯誤處理程序。
Note that proper exception handling in SQL PL dictates that each procedure has an error handler that could easily enough have told us the failing procedure.
注意，SQL PL 中適當?shù)漠惓Ｌ幚硪竺總€過程有一個錯誤處理程序，這個錯誤處理程序應該可以很容易地告訴我們出錯的過程。
