Well, you should at least try to catch the possiblity of a
NumberFormatException when doing Integer.valueOf(String)
In fact, you should be using Integer.parseInt(String) instead .. like this:
protected int handleGetPoolWidth()
{
int poolWidth = 0;
Object taggedValueObject = findTaggedValue("@andromda.tran.width");
if (taggedValueObject != null)
{
poolWidth = Integer.parseInt(String.valueOf(taggedValueObject));
}
return poolWidth;
}
-- Wouter
A few rethorical questions:
Ps1: why don't you catch the exception ? you need to because
String.valueOf(null) = "null"
Ps2: why are you casting zero (0) to an integer ?
