public static OverlapUtil.Slice computeBlockSlice(long blockStart,
 int blockSize,
 long spanStart,
 long spanEnd)

Compute overlap slice into the current block for a span [spanStart, spanEnd).

Parameters:

blockStart - absolute sample index of the first sample in the block.

blockSize - number of samples in this block.

spanStart - absolute start of the span (inclusive).

spanEnd - absolute end of the span (exclusive).

Returns:

a Slice indicating [startIndex, endIndex) within the block, or hasOverlap=false if none.
