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.

方法概要

修饰符和类型	方法	说明
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?

方法详细资料

isMutable

boolean isMutable()

Can the internal state of instances of T be changed?

返回:

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

deepCopy

T deepCopy(T value)

Return a deep copy of the value.

参数:

value - The value to deep copy

返回:

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)

参数:

value - The value to disassemble

返回:

The disassembled value.

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)

参数:

cached - The disassembled state

返回:

The re-assembled value.
