Spring RTS Engine

Is it possible to determine unit's explosion type (C++ native AI)?
Particularly explosion radius is of interest to me.
I see "explodeAs" in lua unit files, but can't find anything related in springai::UnitDef.
Am i missing something or there is no such thing in C++ interface and should i add it?

"explodeAs" refers to a weapon, so you will find it not in unitDef but must look in a weaponDef.
In java there is http://spring.abma.de/doc-Interface-Jav ... onDef.html
"getAreaOfEffect()"
(For C++ do not know where to look.)

Thats right, C++ has WeaponDef::GetAreaOfEffect too. But how can i get value of "explodeAs" in C++/Java? Parse lua files?
Does lua's AI can get "explodeAs" from UnitDef (then i'll add similar API to C++/Java interface)?

UnitDef::GetDeathExplosion and GetSelfDExplosion returns
$$deprecated$$
Why they were deprecated when there is no substitution for them?
