useObjectEqualsHashCode

public boolean useObjectEqualsHashCode()

Description copied from interface: JavaType

Whether to use Object.equals(Object) and Object.hashCode() or JavaType.areEqual(Object, Object) and JavaType.extractHashCode(Object) for objects of this java type. This is useful to avoid mega-morphic callsites.

toString

public String toString(String value)

fromString

public String fromString(CharSequence string)

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators stdIndicators)

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:

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 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> 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

Determines if this Java type is wider than the given Java type, that is, if the given type can be safely widened to this type.

coerce

public <X> String coerce(X value,
                         JavaType.CoercionContext coercionContext)
