Subject: Re: [Boost-users] multi_array_ref (lack of) default constructor

Multi_array view has not default constructor, so I'm stuck with the
same problem.
I guess in the end this is a matter of taste. multi_array seems to be
designed so that objects are always valid at all time.
I'm sure it has lots of advantages, still, for lightweight object such
as a view or multi_array_ref, that might not be necessary.
Ok, I think the only solution left is to use pointers to
multi_array_ref, that should work.
I'd be able to do something along that line (not tested):
std::vector<int> memoryChunk0;
std::vector<int> memoryChunk1;
{
std::vector<multi_array_ref*> v;
v.push_back(new multi_array_ref( <ctor from memoryChunk0 > ));
v.push_back(new multi_array_ref( <ctor from memoryChunk1 >));
myFunction(v);
BOOST_FOREACH( multi_array_ref* ma, v)
{
delete ma;
}
}
