|
|
* Abstract:
|
|
*
|
|
* This class contains definitions of functions which can't (or shouldn't)
|
|
* be inlined. We use a separate implementation class because this allows us
|
|
* to avoid the code bloat template classes produce; every instance of the
|
|
* DynArray template can use the same version of each out-of-line member.
|
|
*
|
|
* The DynArray data members need to be declared here, because they are
|
|
* used by DynArrayImpl.
