public ByteBasedBitPackingEncoder(int bitWidth,
                                  Packer packer)
```
    Parameters:
    
    bitWidth - the number of bits used to encode an int
    
    packer - factory for bit packing implementations
- Method Detail
  - writeInt
```
public void writeInt(int value)
              throws IOException
```
    writes an int using the requested number of bits. accepts only values less than 2^bitWidth
    
    Parameters:
    
    value - the value to write
    
    Throws:
    
    IOException - if there is an exception while writing
  - toBytes
```

                                            throws IOException
```
    Returns:
    
    the bytes representing the packed values
    
    Throws:
    
    IOException - if there is an exception while creating the BytesInput
