are you sure it's necessary to define this outside of this header file?

[bondd, 2015/11/18 01:59:39]

Yes. If I get rid of the constructor and destructor I get:
error: [chromium-style] Complex class/struct needs an explicit out-of-line
constructor.
error: [chromium-style] Complex class/struct needs an explicit out-of-line
destructor.

If I try to define inline implementations like this:
    LegalMessageLine() {};
    ~LegalMessageLine() {};

I get:
error: [chromium-style] Complex constructor has an inlined body.
error: [chromium-style] Complex destructor has an inline body.
