final class RoaringBitmapArray extends Equals

A 64-bit extension of RoaringBitmap that is optimized for cases that usually fit within a 32-bit bitmap, but may run over by a few bits on occasion.

This focus makes it different from org.roaringbitmap.longlong.Roaring64NavigableMap and org.roaringbitmap.longlong.Roaring64Bitmap which focus on sparse bitmaps over the whole 64-bit range.

Structurally, this implementation simply uses the most-significant 4 bytes to index into an array of 32-bit RoaringBitmap instances. The array is grown as necessary to accommodate the largest value in the bitmap.

*Note:* As opposed to the other two 64-bit bitmap implementations mentioned above, this implementation cannot accommodate Long values where the most significant bit is non-zero (i.e., negative Long values). It cannot even accommodate values where the 4 high-order bytes are Int.MaxValue, because then the length of the bitmaps array would be a negative number (Int.MaxValue + 1).
