捕获Exception类而不是Exception子类是不好的做法?(Is it bad practice to catch the Exception class instead of Exception sub-classes?)

我有一个抛出Exception子类的方法。 如果我为Exception的每个子类执行相同的catch功能,那么只是捕获E​​xceptions类或者我应该单独捕获每个异常是不好的做法吗?


I have a method which throws subclasses of Exception. If I am performing the same catch functionality for each sub-class of Exception that's causght is it bad practice to just catch the Exceptions class or should I catch each exception individually ?

最满意答案

您应该在项呈示器的数据设置器中执行此操作:

public override function set data(val:Object):void{
    super.data=val;
    if ((AdvancedDataGrid(listData.owner).columns[listData.columnIndex].
                showDataTips)&&(textWidth>width))
            toolTip=listData.label;
        else toolTip=null;

    }

I solved it. The trick is to use validateSize for the width property. validateProperties is for properties that don't belong to any of the other groups for which there's a dedicated validateX function (such as validateSize, validateList, etc.).
