Throws:

BadLocationException

getBaseX

public int getBaseX(int y)

viewToModel

public int viewToModel(JTextComponent c,
                       int x,
                       int y)

damageRange

public void damageRange(JTextComponent t,
                        int p0,
                        int p1,
