public ByteBuf writeZero(int length)
```
    Description copied from class: ByteBuf
    
    Fills this buffer with NUL (0x00) starting at the current writerIndex and increases the writerIndex by the specified length. If this.writableBytes is less than length, ByteBuf.ensureWritable(int) will be called in an attempt to expand capacity to accommodate.
    
    Overrides:
    
    writeZero in class AbstractByteBuf
    
    Parameters:
    
    length - the number of NULs to write to the buffer

  - isContiguous
```
public boolean isContiguous()
```
    Description copied from class: ByteBuf
    
    Returns true if this ByteBuf implementation is backed by a single memory region. Composite buffer implementations must return false even if they currently hold ≤ 1 components. For buffers that return true, it's guaranteed that a successful call to ByteBuf.discardReadBytes() will increase the value of ByteBuf.maxFastWritableBytes() by the current readerIndex.
    This method will return false by default, and a false return value does not necessarily mean that the implementation is composite or that it is not backed by a single memory region.
    
    Overrides:
