protected ImmutableRoaringArray(java.nio.ByteBuffer bbf)
```
    Create an array based on a previously serialized ByteBuffer. The input ByteBuffer is effectively copied (with the slice operation) so you should expect the provided ByteBuffer position/mark/limit/order to remain unchanged.
    
    参数:
    
    bbf - The source ByteBuffer

  - advanceUntil
```
public int advanceUntil(char x,

```
    从接口复制的说明: PointableRoaringArray
    
    Find the smallest integer index larger than pos such that getKeyAtIndex(index)>=x. If none can be found, return size.
    
    指定者:

  - clone
```
