ensureRemaining
public void ensureRemaining(int requiredRemaining) Ensures the the buffer has at least the requiredRemaining space specified.The internal buffer will be doubled if the requested capacity is less than that amount or the buffer will be expanded to the full new requiredRemaining value.
- Specified by:

- Parameters:
requiredRemaining
- the minimum remaining bytes needed to meet the next write operation.

transferTo
Copy bytes from this buffer into the target buffer and compacts this buffer.Copy either all bytes written into this buffer (start to current position) or as many as will fit if the target capacity is less that the bytes written. Bytes not read from this buffer are moved to the front of the buffer and the position is reset to the end of the copied region.
- Parameters:
target
- The array to move bytes to from those written into this buffer.- Returns:
- the number of bytes transfered to the target buffer.
