  - COLUMN_BITS
```
public static final int COLUMN_BITS
```
    COLUMN_BITS represents how many of the lower-order bits of sourcePosition are reserved for storing the column number. Bits above these store the line number. This gives us decent position information for everything except files already passed through a minimizer, where lines might be longer than 4096 characters.

    Constant Field Values
  - MAX_COLUMN_NUMBER
```
public static final int MAX_COLUMN_NUMBER
```
    MAX_COLUMN_NUMBER represents the maximum column number that can be represented. JSCompiler's modifications to Rhino cause all tokens located beyond the maximum column to MAX_COLUMN_NUMBER.
    
    See Also:
    Constant Field Values
  - COLUMN_MASK
```
public static final int COLUMN_MASK
```
    COLUMN_MASK stores a value where bits storing the column number are set, and bits storing the line are not set. It's handy for separating column number from line number.
