Enum Constant Detail

BOOLEAN_FROM_STRING

public static final BooleanFromResultSet BOOLEAN_FROM_STRING

Reads a string value from the ResultSet using ResultSet.getString(int). The string value is considered to be true iff it is "Y" or "true", ignoring case.

BOOLEAN_FROM_INT

public static final BooleanFromResultSet BOOLEAN_FROM_INT

Reads an int value from the ResultSet using ResultSet.getInt(int). The int value is considered to be true iff it is not zero.

Method Detail

values

public static BooleanFromResultSet[] 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 (BooleanFromResultSet c : BooleanFromResultSet.values())
    System.out.println(c);

Returns:

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

valueOf

public static BooleanFromResultSet 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

getColumnType

public ColumnType<Boolean> getColumnType()

Returns ColumnType.BOOLEAN

Specified by:

getColumnType in interface IFromResultSet<Boolean,BooleanColumnBuilder>

Returns:

ColumnType.BOOLEAN
