public FixedLengthTokenizer()
```
- Method Detail
  - setColumns
```
public void setColumns(Range... ranges)
```
    Set the column ranges. Used in conjunction with the RangeArrayPropertyEditor this property can be set in the form of a String describing the range boundaries, e.g. "1,4,7" or "1-3,4-6,7" or "1-2,4-5,7-10". If the last range is open then the rest of the line is read into that column (irrespective of the strict flag setting).
    Parameters:
    ranges - the column ranges expected in the input
    See Also:
    AbstractLineTokenizer.setStrict(boolean)
  - doTokenize
```
protected java.util.List<java.lang.String> doTokenize(java.lang.String line)
```
    Yields the tokens resulting from the splitting of the supplied line.
    Specified by:
    doTokenize in class AbstractLineTokenizer
    Parameters:
    line - the line to be tokenized (can be null)
    Returns:
    the resulting tokens (empty if the line is null)
    Throws:
    IncorrectLineLengthException - if line length is greater than or less than the max range set.
