void lar::util::details::ResizeToPower2 ( std::vector< T > &  v,
size_t  min_size 
)

Resizes a vector to a size power of 2, with a minimum size.


Parameters
vthe vector to be resized
min_sizethe minimal size of the vector

The vector v is resized, any new element is default-initialized. The target size is the smallest power of 2 not smaller than min_size, or 0 if min_size is 0.
