- All Implemented Interfaces:
CellProcessor
,StringCellProcessor
public class StrMinMax extends CellProcessorAdaptor implements StringCellProcessor
This constraint ensures that the input data has a string length between the supplied min and max values (both inclusive). Should the input be anything different from a String, it will be converted to a string using the input'stoString()
method.- Author:
