[gdal-dev] Initializing vectors

[Kurt Schwehr]

Hi Even,

Trying to get caught up going through patches.  A comment for this one:

https://github.com/OSGeo/gdal/blob/f7c27a807b27cf74cf4666ffe3df4d64cc3f47b3/gdal/frmts/gtiff/geotiff.cpp

You can size and initialize a vector in the constructor.  With this code:

    std::vector<bool> abRequireNewOverview;
    abRequireNewOverview.resize(nOverviews);
    for( int i = 0; i < nOverviews && eErr == CE_None; ++i )
    {
        abRequireNewOverview[i] = true;

The vector can be setup all at one go...

    std::vector<bool> abRequireNewOverview(nOverviews, true);

See http://en.cppreference.com/w/cpp/container/vector/vector  The alloc
will be set to the default.

     vector( size_type count,
                 const T& value,
                 const Allocator& alloc = Allocator());

As for vector<bool>'s sadness, I am not really liking std::bitset for here,
so as long as we are careful, we can use it as long as we are careful not
hit its sharp edges.
