方法详细资料
setColumns
public void setColumns(Range... ranges)
Set the column ranges. Used in conjunction with theRangeArrayPropertyEditorthis 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).- 参数:
ranges- the column ranges expected in the input- 另请参阅:
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 suppliedline.- 指定者:
doTokenize在类中AbstractLineTokenizer- 参数:
line- the line to be tokenized (can benull)- 返回:
- the resulting tokens (empty if the line is null)
- 抛出:
IncorrectLineLengthException- if line length is greater than or less than the max range set.
