Package org.hibernate.type.descriptor.java

Class NClobJavaTypeDescriptor

java.lang.Object

org.hibernate.type.descriptor.java.AbstractClassJavaTypeDescriptor<NClob>

org.hibernate.type.descriptor.java.NClobJavaTypeDescriptor

All Implemented Interfaces:

Serializable, BasicJavaType<NClob>, JavaType<NClob>

public class NClobJavaTypeDescriptor
extends AbstractClassJavaTypeDescriptor<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.

Method Detail

extractLoggableRepresentation

public String extractLoggableRepresentation(NClob value)

Description copied from interface: JavaType

Extract a loggable representation of the value.

Specified by:

extractLoggableRepresentation in interface JavaType<NClob>

Overrides:

extractLoggableRepresentation in class AbstractClassJavaTypeDescriptor<NClob>

Parameters:

value - The value for which to extract a loggable representation.

Returns:

The loggable representation

toString

public String toString(NClob value)

fromString

public NClob fromString(CharSequence string)

extractHashCode

public int extractHashCode(NClob value)

Description copied from interface: JavaType

Extract a proper hash code for this value.

Specified by:

extractHashCode in interface JavaType<NClob>

Overrides:

extractHashCode in class AbstractClassJavaTypeDescriptor<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 interface: JavaType

Determine if two instances are equal

Specified by:

areEqual in interface JavaType<NClob>

Overrides:

areEqual in class AbstractClassJavaTypeDescriptor<NClob>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

getReplacement

public NClob getReplacement(NClob original,
                            NClob target,
                            SharedSessionContractImplementor session)

unwrap

public <X> X unwrap(NClob 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 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: 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.
