Method Detail

values

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

Returns:

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

valueOf

public static PrimitiveType.PrimitiveTypeName 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

toString

public abstract String toString(ColumnReader columnReader)

reads the value from the columnReader with the appropriate accessor and returns a String representation

Parameters:

columnReader - where to read

Returns:

a string

addValueToRecordConsumer

public abstract void addValueToRecordConsumer(RecordConsumer recordConsumer,
                                              ColumnReader columnReader)

reads the value from the columnReader with the appropriate accessor and writes it to the recordConsumer

Parameters:

recordConsumer - where to write

columnReader - where to read from

addValueToPrimitiveConverter

public abstract void addValueToPrimitiveConverter(PrimitiveConverter primitiveConverter,
                                                  ColumnReader columnReader)

convert

public abstract <T,E extends Exception> T convert(PrimitiveType.PrimitiveTypeNameConverter<T,E> converter)
                                                 throws E extends Exception

Throws:

E extends Exception
