java.lang.Object

org.powermock.classloading.DeepCloner

All Implemented Interfaces:

DeepClonerSPI

public class DeepCloner
extends Object
implements DeepClonerSPI

The purpose of the deep cloner is to create a deep clone of an object. An object can also be cloned to a different class-loader.

Clone using the supplied ClassLoader.

DeepCloner

public DeepCloner()

Clone using the current ContextClassLoader.

Method Details

getDoNotClone

clone

public <T> T clone(T objectToClone)

Clones an object.

Specified by:

clone in interface DeepClonerSPI

Returns:

A deep clone of the object to clone.
