<A HREF="../BV/BVRestoreArray.html#BVRestoreArray">BVRestoreArray</A>() must be called when access to the array is no longer needed.
This operation may imply a data copy, for <A HREF="../BV/BV.html#BV">BV</A> types that do not store
data contiguously in memory.
<P>
The pointer will normally point to the first entry of the first column,
but if the <A HREF="../BV/BV.html#BV">BV</A> has constraints then these go before the regular columns.
