- Method Detail
  - copy
```
public static int copy(ByteBuffer source,
                       ByteBuffer destination)
```
    Copies as many bytes as possible from the given source to the destination buffer. The position of both buffers will be incremented by as many bytes as have been copied.
    
    Parameters:
    
    source - ByteBuffer from which bytes are read
    
    destination - ByteBuffer into which bytes are written
    
    Returns:
    
    number of bytes copied, i.e. source.remaining() or destination.remaining(), whatever is less.
  - fill
```
public static int fill(ReadableByteChannel source,
                       ByteBuffer buffer)
                throws IOException
```
    Fills the given buffer by reading from the given source until either reaching EOF or buffer has no more remaining space.
    
    Parameters:
    
    source - The channel to read from
    
    buffer - The buffer to fill
    
    Returns:
    
    Number of bytes read. Will only be less than remaining space in buffer if reaching EOF.
    
    Throws:
    
    IOException - In case of I/O errors
