| | | | | | | | | | | | Instead pass a const Value & into the functions With our new inheritance structure, we can get rid of ValueRef and instead simply pass a pointer to a Value again. Pointers to Values are safe to use again now, as they are now guaranteed to be in a place where the GC knows about them.

* Move vtable out of internalClassLars Knoll2015-01-201-1/+1
| | | | | | | | | | | | | | | | We can move the internalClass to Object later on, and such save having the internalClass on lots of Heap objects. This commit basically adds and starts making use of a new vtable pointer in Heap::Base. In addition, the construction methods in the memory manager now automatically setup the correct vtable. Removing the vtable code from InternalClass and moving it into Object will come in a separate commit Change-Id: If49e8d73c769bf65bf47fe4dbf8b9546c8019dbc Reviewed-by: Simon Hausmann <simon.hausmann@digia.com>

* Fix Managed::as<>() methodLars Knoll2014-07-221-3/+3
| | | | | | | | | | | | | | | The as<> casting method was not doing the right thing in 100% of the cases. It only checked if the object in question was exactly of the type being asked for. It however didn't check if the object was derived from the type. This commit fixes this by adding a parent chain to the vtables, that is then being used to check this safely at runtime.
