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:
