Constructor Detail

AbstractTemporalAccessorParsingProcessor

public AbstractTemporalAccessorParsingProcessor()

Constructs a new AbstractTemporalAccessorParsingProcessor processor, which parses a String as a TemporalAccessor type.

AbstractTemporalAccessorParsingProcessor

public AbstractTemporalAccessorParsingProcessor(CellProcessor next)

Constructs a new AbstractTemporalAccessorParsingProcessor processor, which parses a String as a TemporalAccessor type, then calls the next processor in the chain.

Parameters:

next - the next processor in the chain

Throws:

java.lang.NullPointerException - if next is null

AbstractTemporalAccessorParsingProcessor

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

Constructs a new AbstractTemporalAccessorParsingProcessor processor, which parses a String as a TemporalAccessor type using the supplied formatter.

Parameters:

formatter - the formatter used for parsing

Throws:

java.lang.NullPointerException - if formatter is null

AbstractTemporalAccessorParsingProcessor

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

Constructs a new AbstractTemporalAccessorParsingProcessor processor, which parses a String as a TemporalAccessor type using the supplied formatter, then calls the next processor in the chain.

Parameters:

formatter - the formatter used for parsing

next - the next processor in the chain

Throws:

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

Method Detail

checkPreconditions

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

Checks the preconditions for creating a new AbstractTemporalAccessorParsingProcessor processor.

Parameters:

formatter - the formatter

Throws:

java.lang.NullPointerException - if 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.

Specified by:

execute in interface CellProcessor

Parameters:

value - the value to be processed

context - the CSV context

Returns:

the result of cell processor execution

Throws:

SuperCsvCellProcessorException - if value is null or is not a String

parse

protected abstract T parse(java.lang.String string)

Parses the String into the appropriate TemporalAccessor type.

Parameters:

string - the string to parse

Returns:

the TemporalAccessor type

Throws:

java.lang.IllegalArgumentException - if the string can't be parsed

parse

protected abstract T parse(java.lang.String string,
                           java.time.format.DateTimeFormatter formatter)

Parses the String into the appropriate TemporalAccessor type, using the supplied formatter.

Parameters:

string - the string to parse

formatter - the formatter to use

Returns:

the TemporalAccessor type

Throws:

java.lang.IllegalArgumentException - if the string can't be parsed
