implements StringProcessor
Class Inheritance
All Implemented Interfaces
com.opencsv.bean.processor.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.
