Enum Constant Detail

PRIMITIVE

public static final CharColumnMapper PRIMITIVE

Map to char. Nulls and empty strings are silently replaced with a null char '\0'.

WRAPPER

public static final CharColumnMapper WRAPPER

Map to Character. Nulls and empty strings are replaced with a null reference.

Method Detail

charFromString

public Character charFromString(String s)

mapColumn

public Character mapColumn(ResultSet r,
                           int columnNumber,
                           StatementContext ctx)
                    throws SQLException

Description copied from interface: ResultColumnMapper

Map the given column of the current row of the result set to an Object. This method should not cause the result set to advance, allow jDBI to do that, please.

Specified by:

mapColumn in interface ResultColumnMapper<Character>

Parameters:

r - the result set being iterated

columnNumber - the column number to map (starts at 1)

Returns:

the value to return for this column

Throws:

SQLException - if anything goes wrong go ahead and let this percolate, jDBI will handle it

mapColumn

public Character mapColumn(ResultSet r,
                           String columnLabel,
                           StatementContext ctx)
                    throws SQLException

Description copied from interface: ResultColumnMapper

Map the given column of the current row of the result set to an Object. This method should not cause the result set to advance, allow jDBI to do that, please.

Specified by:

mapColumn in interface ResultColumnMapper<Character>

Parameters:

r - the result set being iterated

columnLabel - the column label to map

Returns:

the value to return for this column

Throws:

SQLException - if anything goes wrong go ahead and let this percolate, jDBI will handle it

valueOf

public static CharColumnMapper valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

values

public static CharColumnMapper[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CharColumnMapper c : CharColumnMapper.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared
