Constructor Detail

AbstractTemporalAccessorFormattingProcessor

public AbstractTemporalAccessorFormattingProcessor()

Constructs a new AbstractTemporalAccessorFormattingProcessor processor, which formats the type as a String.

AbstractTemporalAccessorFormattingProcessor

public AbstractTemporalAccessorFormattingProcessor(CellProcessor next)

Constructs a new AbstractTemporalAccessorFormattingProcessor processor, which formats the type as a String, then calls the next processor in the chain.

Parameters:

next - next processor in the chain

Throws:

java.lang.NullPointerException - if temporalAccessor or next is null

AbstractTemporalAccessorFormattingProcessor

public AbstractTemporalAccessorFormattingProcessor(java.time.format.DateTimeFormatter formatter)

Constructs a new AbstractTemporalAccessorFormattingProcessor processor, which formats the type as a String using the supplied formatter.

Parameters:

formatter - the formatter to use

Throws:

java.lang.NullPointerException - if temporalAccessor or formatter is null

AbstractTemporalAccessorFormattingProcessor

public AbstractTemporalAccessorFormattingProcessor(java.time.format.DateTimeFormatter formatter,
                                                   CellProcessor next)

Constructs a new AbstractTemporalAccessorFormattingProcessor processor, which formats the type as a String using the supplied formatter, then calls the next processor in the chain.

Parameters:

formatter - the formatter to use

next - the next processor in the chain

Throws:

java.lang.NullPointerException - if temporalAccessor, formatter or next is null

Method Detail

checkPreconditions

private static void checkPreconditions(java.time.format.DateTimeFormatter formatter)

Checks the preconditions for creating a new AbstractTemporalAccessorFormattingProcessor processor.

Parameters:

formatter - the formatter

Throws:

java.lang.NullPointerException - if temporalAccessor or formatter is null

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.

Parameters:

value - the value to be processed

context - the CSV context

Returns:

the result of cell processor execution

Throws:

SuperCsvCellProcessorException - if value is null, not the correct type, or can't be formatted

getType

protected abstract java.lang.Class<T> getType()

Returns:

the type formatted by this subclass
