Method Detail

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators context)

Description copied from interface: BasicJavaType

Obtain the "recommended" SQL type descriptor for this Java type. Often, but not always, the source of this recommendation is the JDBC specification.

Parameters:

context - Contextual information

Returns:

The recommended SQL type descriptor

toString

public String toString(UUID value)

fromString

public UUID fromString(CharSequence string)

getDefaultSqlLength

public long getDefaultSqlLength(Dialect dialect,
                                JdbcType jdbcType)

Description copied from interface: JavaType

The default column length when this Java type is mapped to a SQL data type which is parametrized by length, for example Types.VARCHAR.

Returns:

Size.DEFAULT_LENGTH unless overridden

unwrap

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

Description copied from interface: JavaType

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

As an example, if this is a JavaType<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> UUID wrap(X value,
                     WrapperOptions options)

Description copied from interface: JavaType

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.
