Class NClobTypeDescriptor

java.lang.Object
  extended by org.hibernate.type.descriptor.java.AbstractTypeDescriptor<NClob>
      extended by org.hibernate.type.descriptor.java.NClobTypeDescriptor
All Implemented Interfaces:
Serializable, JavaTypeDescriptor<NClob>

public class NClobTypeDescriptor
extends AbstractTypeDescriptor<NClob>

Descriptor for NClob handling.

Note, nclobs really are mutable (their internal state can in fact be mutated). We simply treat them as immutable because we cannot properly check them for changes nor deep copy them.

Field Detail

INSTANCE

public static final NClobTypeDescriptor INSTANCE
Constructor Detail

NClobTypeDescriptor

public NClobTypeDescriptor()
Method Detail

toString

public String toString(NClob value)

fromString

public NClob fromString(String string)

getComparator

public Comparator<NClob> getComparator()
Description copied from class: AbstractTypeDescriptor
Retrieve the natural comparator for this type.

Specified by:
getComparator in interface JavaTypeDescriptor<NClob>
Overrides:
getComparator in class AbstractTypeDescriptor<NClob>
Returns:
The natural comparator.

extractHashCode

public int extractHashCode(NClob value)
Description copied from class: AbstractTypeDescriptor
Extract a proper hash code for this value.

Specified by:
extractHashCode in interface JavaTypeDescriptor<NClob>
Overrides:
extractHashCode in class AbstractTypeDescriptor<NClob>
Parameters:
value - The value for which to extract a hash code.
Returns:
The extracted hash code.

areEqual

public boolean areEqual(NClob one,
                        NClob another)
Description copied from class: AbstractTypeDescriptor
Determine if two instances are equal

Specified by:
areEqual in interface JavaTypeDescriptor<NClob>
Overrides:
areEqual in class AbstractTypeDescriptor<NClob>
Parameters:
one - One instance
another - The other instance
Returns:
True if the two are considered equal; false otherwise.

unwrap

public <X> X unwrap(NClob value,
                    Class<X> type,
                    WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
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> NClob wrap(X value,
                      WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
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.
