Package org.hibernate.type.descriptor.converter

Class AttributeConverterMutabilityPlanImpl<T>

java.lang.Object

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

org.hibernate.type.descriptor.converter.AttributeConverterMutabilityPlanImpl<T>

All Implemented Interfaces:

Serializable, MutabilityPlan<T>

public class AttributeConverterMutabilityPlanImpl<T>
extends MutableMutabilityPlan<T>

The standard approach for defining a MutabilityPlan for converted (AttributeConverter) values is to always assume that they are immutable to make sure that dirty checking, deep copying and second-level caching all work properly no matter what. That was work done under https://hibernate.atlassian.net/browse/HHH-10111 However a series of approaches to tell Hibernate that the values are immutable were documented as part of https://hibernate.atlassian.net/browse/HHH-10127

Constructor Detail

AttributeConverterMutabilityPlanImpl

public AttributeConverterMutabilityPlanImpl(JpaAttributeConverter converter,
                                            boolean mutable)

Method Detail

isMutable

public boolean isMutable()

Description copied from interface: MutabilityPlan

Can the internal state of instances of T be changed?

Specified by:

isMutable in interface MutabilityPlan<T>

Overrides:

isMutable in class MutableMutabilityPlan<T>

Returns:

True if the internal state can be changed; false otherwise.

deepCopyNotNull

protected T deepCopyNotNull(T value)

Specified by:

deepCopyNotNull in class MutableMutabilityPlan<T>

disassemble

public Serializable disassemble(T value,
                                SharedSessionContract session)

Description copied from interface: MutabilityPlan

Return a disassembled representation of the value. This is used to push values onto the second level cache. Compliment to MutabilityPlan.assemble(java.io.Serializable, org.hibernate.SharedSessionContract)

Specified by:

disassemble in interface MutabilityPlan<T>

Overrides:

disassemble in class MutableMutabilityPlan<T>

See Also:

MutabilityPlan.assemble(java.io.Serializable, org.hibernate.SharedSessionContract)

assemble

public T assemble(Serializable cached,
                  SharedSessionContract session)

Description copied from interface: MutabilityPlan

Assemble a previously disassembled value. This is used when pulling values from the second level cache. Compliment to MutabilityPlan.disassemble(T, org.hibernate.SharedSessionContract)

Specified by:

assemble in interface MutabilityPlan<T>

Overrides:

assemble in class MutableMutabilityPlan<T>

MutabilityPlan.disassemble(T, org.hibernate.SharedSessionContract)
