Interface MutabilityPlan<T>

All Superinterfaces:

Serializable

All Known Implementing Classes:

ArrayMutabilityPlan, BlobTypeDescriptor.BlobMutabilityPlan, CalendarTypeDescriptor.CalendarMutabilityPlan, ClobTypeDescriptor.ClobMutabilityPlan, DateTypeDescriptor.DateMutabilityPlan, ImmutableMutabilityPlan, JdbcDateTypeDescriptor.DateMutabilityPlan, JdbcTimestampTypeDescriptor.TimestampMutabilityPlan, JdbcTimeTypeDescriptor.TimeMutabilityPlan, MutableMutabilityPlan, NClobTypeDescriptor.NClobMutabilityPlan, SerializableTypeDescriptor.SerializableMutabilityPlan

public interface MutabilityPlan<T>
extends Serializable

Describes the mutability aspects of a Java type. The term mutability refers to the fact that generally speaking the aspects described by this contract are defined by whether the Java type's internal state is mutable or not.

Method Summary

Methods

Modifier and Type	Method and Description
T	assemble(Serializable cached) Assemble a previously disassembled value.
T	deepCopy(T value) Return a deep copy of the value.
Serializable	disassemble(T value) Return a "disassembled" representation of the value.
boolean	isMutable() Can the internal state of instances of T be changed?

Method Detail

isMutable

boolean isMutable()

Can the internal state of instances of T be changed?

Returns:

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

deepCopy

T deepCopy(T value)

Return a deep copy of the value.

Parameters:

value - The value to deep copy

Returns:

The deep copy.

disassemble

Serializable disassemble(T value)

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

Parameters:

value - The value to disassemble

Returns:

The disassembled value.

assemble(java.io.Serializable)

assemble

T assemble(Serializable cached)

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

Parameters:

cached - The disassembled state

Returns:

The re-assembled value.
