EnumJavaType

public EnumJavaType(Class<T> type)

Method Detail

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators context)

Description copied from interface: BasicJavaType

Obtain the "recommended" SQL type descriptor for this Java type. The recommended aspect comes from the JDBC spec (mostly).

Parameters:

context - Contextual information

Returns:

The recommended SQL type descriptor

toString

public String toString(T value)

fromString

public T fromString(CharSequence string)

unwrap

public <X> X unwrap(T 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> T 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.

fromName

public T fromName(String relationalForm)

Interpret a String value as the named value of the enum type

getCheckCondition

public String getCheckCondition(String columnName,
                                JdbcType jdbcType,
                                Dialect dialect)

Description copied from interface: JavaType

The check constraint that should be added to the column definition in generated DDL.

Parameters:

columnName - the name of the column

jdbcType - the JdbcType of the mapped column

dialect - the SQL Dialect

Returns:

a check constraint condition or null
