The const_cast in Deck::get*UnitSystem are potentially undefined
behaviour under a series of (plausible) conditions, and are deprecated
in favour of mutable members. Removes initUnitSystem from the public
interface, as the initialisation is handled on the first getUnitSystem
anyway, cleaning up the Deck interface slightly.
Adds proper constness to the use of unit systems that don't actually
modify the internal state in any way.
Since the Deck* family of classes have changed their interfaces to no
longer use shared_ptr, a lot of code broke. This patch fixes all
problems in tests, other signatures and accesses to now use the new Deck
interfaces.
Every header is self-contained and includes only what it must to
function, relying on users include what they need in source files,
adopting a pay-what-you-use model (in particular for internal
dependencies).
To reduce compiler stress and be more explicit w.r.t. dependencies, all
files now includes only the keywords they need, instead of the
collection of all files.
This is an effort to improve build performance. Several includes
scattered across the project are either unused or partially used (i.e.
just used to import a type name, not depending on the actual contents of
the header file).
Replaces a lot of these includes with forward declarations.
Main change is in VFPPRod::getALQTYpe() where we use the
DeckItem::defaultApplied() method instead of comparing with the special
default value ' '. The other functions are changed just to be consistent.
