FindBugs issue with transient
in [Java Programming]
|
From: Paul Tomblin on 22 Jul 2008 21:38 I just insalled the FindBugs plugin in Eclipse, and while it whines about a bunch of stuff that I don't care about, it's found a few real ones. But there is a warning that I don't understand at all. A transient variable in a serializable class is marked: H B Se: The field <variable name> is transient but isn't set by deserialization. What does that mean? -- Paul Tomblin <ptomblin(a)xcski.com> http://blog.xcski.com/ Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway. -- Andrew Tannenbaum possibly quoting Warren Jackson

I initialize the variable in the default ctor. Would it be happier if I initialized it in the declaration line? -- Paul Tomblin <ptomblin(a)xcski.com> http://blog.xcski.com/ Can't get out of 'vi'? Common problem. Don't worry, I'm here to help. Just log in as root and type "init 0". It works for pretty much any problem you might have with Linux. No, no, no. Thank /you/. -- Mikey Raeder
