Method Detail

toString

public String toString(T value)

fromString

public T fromString(String string)

unwrap

public <X> X unwrap(T value,
                    Class<X> type,
                    WrapperOptions options)

Description copied from interface: JavaTypeDescriptor

Unwrap an instance of our handled Java type into the requested type.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap the Integer value as a Long we would return something like Long.valueOf( value.longValue() ).

Intended use is during PreparedStatement binding.

Type Parameters:

X - The conversion type.

Parameters:

value - The value to unwrap

type - The type as which to unwrap

options - The options

Returns:

The unwrapped value.

wrap

public <X> T wrap(X value,
                  WrapperOptions options)

Description copied from interface: JavaTypeDescriptor

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Type Parameters:

X - The conversion type.

Parameters:

value - The value to wrap.

options - The options

Returns:

The wrapped value.

toOrdinal

public <E extends Enum> Integer toOrdinal(E domainForm)

fromOrdinal

public <E extends Enum> E fromOrdinal(Integer relationalForm)

fromName
