Method Details

isInstance

public boolean isInstance(Object value)

Description copied from interface: JavaType

Is the given value an instance of the described type?

Usually just getJavaTypeClass().isInstance(value), but some descriptors need specialized semantics, for example, the descriptors for java.sql.Date, java.sql.Time, and java.sql.Timestamp.

For EntityJavaType, this method handles proxies in a semantically correct way, by checking the entity instance underlying the proxy object.

cast

public Year cast(Object value)

Description copied from interface: JavaType

Apply a simple type cast to the given value, without attempting any sort of coercion or wrapping. This method is provided as a convenient way to avoid an unchecked cast to a type variable. Use javaType.cast(value) instead of (T) value wherever possible.

Usually just getJavaTypeClass().cast(value), but overridden in some cases as an "optimization". This optimization is almost certainly unnecessary, and might even indeed be harmful, since Class.cast() is an intrinsic.

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

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(Year value)

fromString

public Year fromString(CharSequence string)

unwrap

public <X> X unwrap(Year 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> Year 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.
