Constructor Detail

FieldCloner

public FieldCloner(Cloner defaultCloner,
                   InstanceProvider instanceProvider)

Constructs a field cloner that copies objects by reading and writing the internal fields directly.

Parameters:

defaultCloner - - the default cloner used while copying fields.

instanceProvider - - used to construct new, empty copies of a given type.

Method Detail

defaultTransform

protected void defaultTransform(StructureModifier<Object> modifierSource,
                                StructureModifier<Object> modifierDest,
                                Cloner defaultCloner,
                                int fieldIndex)

Default implementation of the field transform. Applies a clone operation before a field value is written.

Parameters:

modifierSource - - modifier for the original object.

modifierDest - - modifier for the new cloned object.

defaultCloner - - cloner to use.

fieldIndex - - the current field index.

canClone

public boolean canClone(Object source)

Description copied from interface: Cloner

Determine whether or not the current cloner can clone the given object.

Specified by:

canClone in interface Cloner

Parameters:

source - - the object that is being considered.

Returns:

TRUE if this cloner can actually clone the given object, FALSE otherwise.

clone

public Object clone(Object source)

Description copied from interface: Cloner

Perform the clone.

This method should never be called unless a corresponding Cloner.canClone(Object) returns TRUE.

Specified by:

clone in interface Cloner

Parameters:

source - - the value to clone.

Returns:

A cloned value.

getDefaultCloner

public Cloner getDefaultCloner()

Retrieve the default cloner used to clone the content of each field.

Returns:

Cloner used to clone fields.

getInstanceProvider

public InstanceProvider getInstanceProvider()

Retrieve the instance provider this cloner is using to create new, empty classes.

Returns:

The instance provider in use.
