Package org.hibernate.type.descriptor.java

Class JdbcDateJavaType

java.lang.Object

org.hibernate.type.descriptor.java.AbstractClassJavaType<T>

org.hibernate.type.descriptor.java.AbstractTemporalJavaType<Date>

org.hibernate.type.descriptor.java.JdbcDateJavaType

All Implemented Interfaces:

Serializable, BasicJavaType<Date>, JavaType<Date>, TemporalJavaType<Date>

public class JdbcDateJavaType
extends AbstractTemporalJavaType<Date>

Descriptor for Date handling.

See Also:

Serialized Form

"Implementation Specification:"

Unlike most JavaType implementations, can handle 2 different "domain representations" (most map just a single type): general Date values in addition to Date values. This capability is shared with JdbcTimeJavaType and JdbcTimestampJavaType.

JdbcDateJavaType

public JdbcDateJavaType()

Method Detail

getPrecision

public TemporalType getPrecision()

Description copied from interface: TemporalJavaType

The precision represented by this type

isInstance

public boolean isInstance(Object value)

Description copied from interface: JavaType

Is the given value an instance of the described type? Generally this comes down to getJavaTypeClass().isInstance(), though some descriptors (mainly the java.sql.Date, Time and Timestamp descriptors) might need different semantics

areEqual

public boolean areEqual(Date one,
                        Date another)

Description copied from interface: JavaType

Determine if two instances are equal

Specified by:

areEqual in interface JavaType<Date>

Overrides:

areEqual in class AbstractClassJavaType<Date>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(Date value)

Description copied from interface: JavaType

Extract a proper hash code for this value.

Specified by:

extractHashCode in interface JavaType<Date>

Overrides:

extractHashCode in class AbstractClassJavaType<Date>

Parameters:

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

Returns:

The extracted hash code.

coerce

public Date coerce(Object value,
                   JavaType.CoercionContext coercionContext)

unwrap

public Object unwrap(Date value,
                     Class 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.

Parameters:

value - The value to unwrap

type - The type as which to unwrap

options - The options

Returns:

The unwrapped value.

wrap

public Date wrap(Object value,
                 WrapperOptions options)

Description copied from interface: JavaType

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Parameters:

value - The value to wrap.

options - The options

Returns:

The wrapped value.

toString

public String toString(Date value)

fromString

public Date fromString(CharSequence string)

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

forDatePrecision

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

Overrides:

forDatePrecision in class AbstractTemporalJavaType<Date>
