Class CollectionJavaType<C>

java.lang.Object

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

org.hibernate.type.descriptor.java.spi.CollectionJavaType<C>

All Implemented Interfaces:

Serializable, BasicJavaType<C>, JavaType<C>

public class CollectionJavaType<C>
extends AbstractClassJavaType<C>

Extension of the general JavaType for "collection types"

See Also:

• CollectionSemantics
• Serialized Form

API Note:

"Collection types" are defined loosely here to cover mapping collection types other than those from the "Java Collection Framework".

Method Details

getSemantics

public CollectionSemantics<C,?> getSemantics()

getRecommendedJdbcType

public JdbcType getRecommendedJdbcType(JdbcTypeIndicators context)

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:

context - Contextual information

Returns:

The recommended SQL type descriptor

createJavaType

public JavaType<C> createJavaType(ParameterizedType parameterizedType,
 TypeConfiguration typeConfiguration)

Description copied from interface: JavaType

Creates the JavaType for the given ParameterizedType based on this JavaType registered for the raw type.

fromString

public C fromString(CharSequence string)

unwrap

public <X> X unwrap(C 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> C 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.

areEqual

public boolean areEqual(C one,
 C another)

Description copied from interface: JavaType

Determine if two instances are equal

Specified by:

areEqual in interface JavaType<C>

Overrides:

areEqual in class AbstractClassJavaType<C>

Parameters:

one - One instance

another - The other instance

Returns:

True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(C x)

Description copied from interface: JavaType

Extract a proper hash code for the given value.

Specified by:

extractHashCode in interface JavaType<C>

Overrides:

extractHashCode in class AbstractClassJavaType<C>

Parameters:

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

Returns:

The extracted hash code.
