Method Details

parseBigInteger

public static BigInteger parseBigInteger(String str)
                                  throws SQLDataException

Parse a numeric string into a BigInteger, rejecting inputs longer than BigDecimalCodec.MAX_BIG_DECIMAL_STRING_LENGTH characters. Mirrors BigDecimalCodec.parseBigDecimal(String) — same cap applies because new BigInteger(String) shares the O(n²) cost of new BigDecimal(String).

Parameters:

str - numeric text

Returns:

parsed BigInteger

Throws:

SQLDataException - if str is longer than the cap

NumberFormatException - if str isn't a valid integer

className

public String className()

Description copied from interface: Codec

Codec native type

Specified by:

className in interface Codec<BigInteger>

Returns:

code native return type

canDecode

public boolean canDecode(ColumnDecoder column,
 Class<?> type)

Description copied from interface: Codec

If codec can decode this a server datatype to a java class type

Specified by:

canDecode in interface Codec<BigInteger>

Parameters:

column - server datatype

type - java return class

Returns:

true if codec can decode it

canEncode

public boolean canEncode(Object value)

Description copied from interface: Codec

Can Codec encode the java object type

Specified by:

canEncode in interface Codec<BigInteger>

Parameters:

value - java object type

Returns:

true if codec can encode java type

decodeText

Specified by:

decodeText in interface Codec<BigInteger>

Parameters:

buf - mysql packet buffer

length - encoded value length

column - server column metadata

cal - calendar

context - connection context

Returns:
