Class ConvertWordNullToNull

java.lang.Object

com.opencsv.bean.processor.ConvertWordNullToNull

All Implemented Interfaces:

StringProcessor

public class ConvertWordNullToNull
extends Object
implements StringProcessor

StringProcessor that converts the string value "null" to a literal null string. This is useful when you are dealing with csv files that actually use the word null.

A sample of this can be found in the Integration tests FR138MockBean and is annotated as follows.

     @PreAssignmentProcessor(processor = ConvertWordNullToNull.class)
     private int num;
 

Without the annotation an CSVMalformedException is thrown when trying to conver the string "null" to an int. But with it is considered a null String and the int gets a default value of 0.
