text
- JTextComponent containing textpos
- Position used in determining next positionbias
- Bias used in determining next positiondirection
- the direction from the current position that can
be thought of as the arrow keys typically found on a keyboard.
This will be one of the following values:
biasRet
- Used to return resulting Bias of next position
BadLocationException
IllegalArgumentException
- if direction
doesn't have one of the legal values above
