the next processor in the chain

Constructor Detail

CellProcessorAdaptor

protected CellProcessorAdaptor()

Constructor used by CellProcessors to indicate that they are the last processor in the chain.

CellProcessorAdaptor

protected CellProcessorAdaptor(CellProcessor next)

Constructor used by CellProcessors that require CellProcessor chaining (further processing is required).

Parameters:

next - the next CellProcessor in the chain

Throws:

NullPointerException - if next is null

Method Detail

validateInputNotNull

protected void validateInputNotNull(Object value,
                                    CsvContext context)

Parameters:

value - the input value

context - the CSV context

Throws:

SuperCsvCellProcessorException - if value is null
