Class DMinMax
- java.lang.Object
-
- org.supercsv.cellprocessor.CellProcessorAdaptor
-
- org.supercsv.cellprocessor.constraint.DMinMax
-
- All Implemented Interfaces:
CellProcessor
,StringCellProcessor
public class DMinMax extends CellProcessorAdaptor implements StringCellProcessor
Converts the input data to a Double and ensures that number is within a specified numeric range (inclusive). If the data has no upper bound (or lower bound), you should use either ofMIN
orMAX
constants provided in the class.- Author:

execute
public java.lang.Object execute(java.lang.Object value, CsvContext context)
This method is invoked by the framework when the processor needs to process data or check constraints.- Specified by:
execute
in interfaceCellProcessor
- Parameters:
value
- the value to be processedcontext
- the CSV context- Returns:
- the result of cell processor execution
- Throws:
SuperCsvCellProcessorException
- if value is null or can't be parsed as a DoubleSuperCsvConstraintViolationException
- if value doesn't lie between min and max (inclusive)
