Method Details

getPrecision

public TemporalType getPrecision()

Description copied from interface: TemporalJavaType

The precision represented by this type

Specified by:

getPrecision in interface TemporalJavaType<Calendar>

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators context)

Description copied from interface: JavaType

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

Specified by:

getRecommendedJdbcType in interface BasicJavaType<Calendar>

Specified by:

getRecommendedJdbcType in interface JavaType<Calendar>

Parameters:

context - Contextual information

Returns:

The recommended SQL type descriptor

forTimestampPrecision

protected <X> TemporalJavaType<X> forTimestampPrecision(TypeConfiguration typeConfiguration)

Overrides:

forTimestampPrecision in class AbstractTemporalJavaType<Calendar>

forDatePrecision

protected <X> TemporalJavaType<X> forDatePrecision(TypeConfiguration typeConfiguration)

Overrides:

forDatePrecision in class AbstractTemporalJavaType<Calendar>

forTimePrecision

protected <X> TemporalJavaType<X> forTimePrecision(TypeConfiguration typeConfiguration)

Overrides:

forTimePrecision in class AbstractTemporalJavaType<Calendar>

toString

public String toString(Calendar value)

Specified by:

toString in interface JavaType<Calendar>

fromString

public Calendar fromString(CharSequence string)

Specified by:

fromString in interface BasicJavaType<Calendar>

Specified by:

fromString in interface JavaType<Calendar>

areEqual

public boolean areEqual(Calendar one,
 Calendar another)

Description copied from interface: JavaType

Determine if two instances are equal

Specified by:

areEqual in interface JavaType<Calendar>

Overrides:

areEqual in class AbstractClassJavaType<Calendar>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(Calendar value)

Description copied from interface: JavaType

Extract a proper hash code for the given value.

Specified by:

extractHashCode in interface JavaType<Calendar>

Overrides:

extractHashCode in class AbstractClassJavaType<Calendar>

Parameters:

value - The value for which to extract a hash code.

Returns:

The extracted hash code.

unwrap

public <X> X unwrap(Calendar 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.

Specified by:

unwrap in interface JavaType<Calendar>

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> Calendar wrap(X value,
 WrapperOptions options)

Description copied from interface: JavaType

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Specified by:

wrap in interface JavaType<Calendar>

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.

Specified by:

isWider in interface JavaType<Calendar>

getDefaultSqlPrecision

public int getDefaultSqlPrecision(Dialect dialect,
 JdbcType jdbcType)

Description copied from interface: JavaType

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

Specified by:

getDefaultSqlPrecision in interface JavaType<Calendar>

Returns:

Size.DEFAULT_PRECISION unless overridden

next

public Calendar next(Calendar current,
 Long length,
 Integer precision,
 Integer scale,
 SharedSessionContractImplementor session)

Description copied from interface: VersionJavaType

Increment the version.

Specified by:

next in interface VersionJavaType<Calendar>

Parameters:

current - the current version

length - The length of the type

precision - The precision of the type

scale - The scale of the type

session - The session from which this request originates.

Returns:

an instance of the type

seed

public Calendar seed(Long length,
 Integer precision,
 Integer scale,
 SharedSessionContractImplementor session)

Description copied from interface: VersionJavaType

Generate an initial version.

Note that this operation is only used when the program sets a null or negative number as the value of the entity version field. It is not called when the program sets the version field to a sensible-looking version.

Specified by:

seed in interface VersionJavaType<Calendar>

Parameters:

length - The length of the type

precision - The precision of the type

scale - The scale of the type

session - The session from which this request originates.

Returns:

an instance of the type
