Package org.hibernate.type.descriptor.java

Class ClobJavaType

java.lang.Object

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

org.hibernate.type.descriptor.java.ClobJavaType

All Implemented Interfaces:

Serializable, BasicJavaType<Clob>, JavaType<Clob>

public class ClobJavaType
extends AbstractClassJavaType<Clob>

Descriptor for Clob handling.

Note, strictly-speaking a Clob object is actually mutable (its internal state can in fact be mutated). But we treat them as immutable because we simply have no way to dirty check nor deep copy them.

Method Details

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators indicators)

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:

indicators - Contextual information

Returns:

The recommended SQL type descriptor

extractLoggableRepresentation

public String extractLoggableRepresentation(Clob value)

Description copied from interface: JavaType

Extract a loggable representation of the given value.

Specified by:

extractLoggableRepresentation in interface JavaType<Clob>

Overrides:

extractLoggableRepresentation in class AbstractClassJavaType<Clob>

Parameters:

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

Returns:

The loggable representation

toString

public String toString(Clob value)

fromString

public Clob fromString(CharSequence string)

extractHashCode

public int extractHashCode(Clob value)

Description copied from interface: JavaType

Extract a proper hash code for the given value.

Specified by:

extractHashCode in interface JavaType<Clob>

Overrides:

extractHashCode in class AbstractClassJavaType<Clob>

Parameters:

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

Returns:

The extracted hash code.

areEqual

public boolean areEqual(Clob one,
 Clob another)

Description copied from interface: JavaType

Determine if two instances are equal

Specified by:

areEqual in interface JavaType<Clob>

Overrides:

areEqual in class AbstractClassJavaType<Clob>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

getReplacement

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

unwrap

public <X> X unwrap(Clob 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> Clob 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.

getDefaultSqlLength

public long getDefaultSqlLength(Dialect dialect,
 JdbcType jdbcType)

Description copied from interface: JavaType

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

Returns:

Size.DEFAULT_LENGTH unless overridden
