    Description copied from interface: ValueVector
    
    Returns the number of bytes that is used by this vector if it holds the given number of values. The result will be the same as if setValueCount() were called, followed by calling getBufferSize(), but without any of the closing side-effects that setValueCount() implies wrt finishing off the population of a vector. Some operations might wish to use this to determine how much memory has been used by a vector so far, even though it is not finished being populated.
    
    Specified by:
    
    getBufferSizeFor in interface ValueVector
    
    Parameters:
    
    valueCount - the number of values to assume this vector contains
    
    Returns:
    
    the buffer size if this vector is holding valueCount values
  - getBuffers
```
public ArrowBuf[] getBuffers(boolean clear)
```
    Description copied from interface: ValueVector
    
    Return the underlying buffers associated with this vector. Note that this doesn't impact the reference counts for this buffer so it only should be used for in-context access. Also note that this buffer changes regularly thus external classes shouldn't hold a reference to it (unless they change it).
    
    Specified by:
    
    getBuffers in interface ValueVector
    
    Parameters:
    
    clear - Whether to clear vector before returning; the buffers will still be refcounted; but the returned array will be the only reference to them
    
    Returns:
    
    The underlying buffers that is used by this vector instance.
