Method Detail

getSingleton

public static BigIntegerConverter getSingleton()

Get singleton for class.

configure

public DecimalFormat configure(String format,
                               long flags,
                               ColumnInfo<BigInteger> fieldInfo)

Description copied from interface: Converter

Configure this instance of the converter based on the associated params.

Specified by:

configure in interface Converter<BigInteger,DecimalFormat>

Parameters:

format - Optional string format which affects the output and parsing of the field. Null if none supplied in which case the default format is used.

flags - Optional numerical flags which affect the output and parsing of the field. 0 if no flags supplied.

fieldInfo - Information about the field associated with this converter.

Returns:

Information structure or null if none. This will be passed to the other methods.

isNeedsQuotes

public boolean isNeedsQuotes(DecimalFormat decimalFormat)

Description copied from interface: Converter

Returns true if the field needs to be quoted in the CSV output.

Specified by:

isNeedsQuotes in interface Converter<BigInteger,DecimalFormat>

isAlwaysTrimInput

public boolean isAlwaysTrimInput()

Description copied from interface: Converter

Returns true if the field should trim the string before it is passed to Converter.stringToJava(String, int, int, ColumnInfo, String, ParseError).

Specified by:

isAlwaysTrimInput in interface Converter<BigInteger,DecimalFormat>

javaToString

public String javaToString(ColumnInfo<BigInteger> columnInfo,
                           BigInteger value)

Description copied from interface: Converter

Converts from a Java representation to string.

Specified by:

javaToString in interface Converter<BigInteger,DecimalFormat>

Parameters:

columnInfo - Information about the column we are processing.

value - Value of the field that we are converting.

Returns:

The String equivalent object of the value parameter or null in which case nothing will be printed.

stringToJava

public BigInteger stringToJava(String line,
                               int lineNumber,
                               int linePos,
                               ColumnInfo<BigInteger> columnInfo,
                               String value,
                               ParseError parseError)
                        throws ParseException

Description copied from interface: Converter

Converts from a string representation to Java.

Specified by:

stringToJava in interface Converter<BigInteger,DecimalFormat>

Parameters:

line - Line we are processing for logging purposes.

lineNumber - Number of the line we are processing for logging purposes.

linePos - Position in the line that we are converting to identify what part of the line contains the value.

columnInfo - Information about the column we are processing.

value - Value of the field that we are converting.

parseError - Parse error which can we use to set information about parse errors here. If there are no parse errors then just ignore this field. Any exceptions thrown will also be caught and interpreted as errors.

Returns:

The Java equivalent object of the value parameter or null. Null can mean a null value or if the parseError type is set to something other than ParseError.ErrorType.NONE.

Throws:

ParseException - If there was some sort of parse or other error. It is better to return null and use the parseError argument instead. All RuntimeExceptions will be caught as well.
