getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeDescriptorIndicators stdIndicators)

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:

stdIndicators - Contextual information

Returns:

The recommended SQL type descriptor

unwrap

public <X> X unwrap(String 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 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> String 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.

isWider

public boolean isWider(JavaType<?> javaType)

Description copied from interface: JavaType

Returns whether this java type is wider than the given type i.e. if the given type can be widened to this java type.
