MutableMutabilityPlan

public MutableMutabilityPlan()

Method Detail

isMutable

public boolean isMutable()

Can the internal state of instances of T be changed?

Specified by:

isMutable in interface MutabilityPlan<T>

Returns:

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

disassemble

public Serializable disassemble(T value)

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)

Specified by:

disassemble in interface MutabilityPlan<T>

Parameters:

value - The value to disassemble

Returns:

The disassembled value.

See Also:

MutabilityPlan.assemble(java.io.Serializable)

assemble

public T assemble(Serializable cached)

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

Specified by:

assemble in interface MutabilityPlan<T>

Parameters:

cached - The disassembled state

Returns:

The re-assembled value.

See Also:

MutabilityPlan.disassemble(T)

deepCopy

public final T deepCopy(T value)

Description copied from interface: MutabilityPlan

Return a deep copy of the value.

Specified by:

deepCopy in interface MutabilityPlan<T>

Parameters:

value - The value to deep copy

Returns:

The deep copy.

deepCopyNotNull

protected abstract T deepCopyNotNull(T value)
