UnsafeCloneStrategy

public UnsafeCloneStrategy()

Method Detail

newInstance

public <T> T newInstance(Class<T> c)

Description copied from interface: CloneImplementor

Create a new, uninitialised instance of the given class (if supported). Depending on strategy, this may or may not initialise instance fields, and may or may not invoke constructors.

Specified by:

newInstance in interface CloneImplementor

Specified by:

newInstance in class AbstractCloneStrategy

Type Parameters:

T - The type of the instance to be constructed

Parameters:

c - Type to create instance of

Returns:

The new instance

getInstance

public static UnsafeCloneStrategy getInstance()

Returns a shared instance of UnsafeCloneStrategy

Returns:

The instance

getClassModel

protected <W> ClassModel<W> getClassModel(Class<W> clazz)

Description copied from class: AbstractCloneStrategy

Obtain a ClassModel instance for the given class

Specified by:

getClassModel in class AbstractCloneStrategy

Type Parameters:

W - The type of class

Parameters:

clazz - Class to model

Returns:

The ClassModel

handleTransientField

protected <T> void handleTransientField(T copy,
                                        FieldModel<T> f)

Description copied from class: AbstractCloneStrategy

Implementations should ensure that transient fields are left with the correct default (unset) value

Specified by:

handleTransientField in class AbstractCloneStrategy

Type Parameters:

T - The type containing the field

Parameters:

copy - The target object

f - The FieldModel for the Field that should stay as a default

handleClonePrimitiveField

protected <T> void handleClonePrimitiveField(T obj,
                                             T copy,
                                             CloneDriver driver,
                                             FieldModel<T> f,
                                             IdentityHashMap<Object,Object> referencesToReuse)

Description copied from class: AbstractCloneStrategy
